Abstract

Analysis and design of building structures subjected to earthquake forces is complex task as earthquake forces are random in nature & unpredictable. In performance based analysis and design estimation of proper response parameters of structure is priorly considered to evaluate its performance. In the present work performance based analysis and design of building frames with earthquake loading is carried out. The performance of the structure considering potential hazards and uncertainties in assessment of the actual building responses are studied. Performance objectives are selected in performance based analysis and design followed by the development of a preliminary design. Further redesign and reassessment are carried out until the desired performance levels are achieved. Buildings frames are analyzed and redesigned by improving the reinforcement of various components of building frames. Multi storied building frames are analyzed enhancing the reinforcement of structural members in different combination as well as at different storey levels. The results of the analysis and design performed to meet required performance are presented in terms of displacement and forces.

Abstract

Supplier Evaluation and Management is a very strong concept in manufacturing industry, but has to come a long way in the construction Projects. In projects, especially in India, it is considered as a part of the unorganised sector. While developing a supplier survey for the purchaser it is to be decided which performance categories to include. The primary criteria are cost/price, quality and delivery, which are generally the most obvious and most critical areas that affect the buyer. For many items, these three performance areas would be enough, however for critical items needing an in-depth analysis of the supplier's capabilities, a more detailed supplier evaluation study is required. This paper reviews the literature of various approaches for supplier evaluation and selection. Supplier Evaluation and Management initiates them to adopt the most efficient approaches in order to ensure the smooth flow of the execution of the Project. Study puts efforts in effectiveness in selection of vendors and their evaluation.

Abstract

Construction industry is highly risk prone, with complex and dynamic project environments which create an atmosphere of high uncertainty and risk. The industry is vulnerable to various technical, socio-political and business risks. The track record to cope with these risks has not been very good in construction industry. As a result, the people working in the industry bear various failures, such as failure of abiding by quality and operational requirements, cost overruns and uncertain delays in project completion. Risk management is a process which consists of identification of risks, assessment with qualitatively and quantitatively, responses with a suitable method for handling risks, and then controls the risks by monitoring. This paper covers the concepts of risk management and various risk analysis techniques to be used for the one stop solution for all types of hazards most likely to occur during any construction project lifecycle.

Abstract

On ships, tankers and similar vessels structural defects such as cracks and corrosion damage are typically repaired by welding. However, welding is unwanted hotwork on floating offshore units (FOUs) such as floating, production, storage and offloading (FPSO) and floating, storage and offloading (FSO) vessels because it requires shutdown of parts of the vessel thus resulting in expensive production delays. Bonded fibre composite material patch repairs can be used as an alternative to overcome the hazards of hotwork associated with welding. The patches are bonded over the defect and the integrity of the original structure is hence restored. The patch repair technology can also be utilised to provide upgrades, such as life extensions and higher design requirements. A recommended practice (RP) has been developed that describes requirements for patch repairs used in floating offshore units. To provide flexibility and to fit different repair needs, the recommended practice defines a range of Repair Classes that can be used depending on the urgency of the repair and the need for optimisation. The qualification effort increases with the degree of optimisation. Study on Two full-scale repair demonstrators were carried out on actual floating offshore units to demonstrate the feasibility of the recommended practice for bonded composite patch repair. In addition the demonstrators also showed the viability of using bonded composite repairs under harsh conditions encountered in oil and gas exploration and production environments. The first repair was carried out to arrest a fatigue crack that had developed from the corner of a door, while the second repair was carried out to restore material loss on a heavily pitted deck floor. Both repair cases are used as examples to demonstrate the proposed qualification procedures whilst at the same time discussing the challenges and potential applications of this patch repair technology for floating offshore units in the oil and gas industry.

Abstract

Rigid pavements, though costly in initial investment, are cheap in long run because of low maintenance costs. There are various merits in the use of rigid pavements (Concrete pavements) are summarized below. Bitumen is derived from petroleum crude, which is in short supply globally and the price of which has been rising steeply. India imports nearly 70% of the petroleum crude. The demand for bitumen in the coming years is likely to grow steeply, far outstripping the availability. Hence it will be in India's interest to explore alternative binders. Cement is available in sufficient quantity in India, and its availability in the future is also assured. Thus cement concrete roads should be the obvious choice in future road programmes. Besides the easy available of cement, concrete roads have a long life and are practically maintenance-free. Another major advantage of concrete roads is the savings in fuel by commercial vehicles to an extent of 14-20%. The fuel savings themselves can support a large programme of concreting. Cement concrete roads save a substantial quantity of stone aggregates and this factor must be considered when a choice pavement is made, Concrete roads can withstand extreme weather conditions-wide ranging temperatures, heavy rainfall and water logging. Though cement concrete roads may cost slightly more than a flexible pavement initially, they are economical when whole-life-costing is considered. Reduction in the cost of concrete pavements can be brought about by developing semi-self-compacting concrete techniques and the use of closely spaced thin joints. Research and development R&D efforts should be initiated in this area.

Abstract

Concrete is the most widely used construction material having desirable properties like high compressive strength, stiffness and durability under usual environmental condition. Also concrete is brittle and weak in tension. Plain concrete has low tensile strength and a low strain at fracture. These shortcomings have been overcome by reinforcing concrete. The properties of ordinary cement concrete are generally improved to a great extent by latex modification. Hardened cement paste mainly has an agglomerated structure of calcium silicate hydrated and calcium hydroxide bound together by the weaker forces, and therefore, micro cracks occur easily in the paste under stress. This leads to poor tensile strength and fracture toughness of ordinary cement mortar and concrete. In the present work, experimental test are carried out to calculate compression strength on cube, flexural strength on beam, spilt tensile strength on cylinder and pull out test on cube with embedded steel bar. Casting of the specimen is done in laboratory using 15% polymer (styrene butadiene rubber) with 1% to 10% of the hooked end steel fiber. The 16 mm diameter bars are used in the pull out test. All the test on hardened concrete is carried out as per the IS code of the respective test, Specimen to be casted. It is observed that by contras in the polymer modified concrete micro cracks are bridged by the polymer film on membranes which prevent cracks propagation and simultaneously a strong cement hydrate- aggregate bond is developed. As per result flexural strength and bond strength of concrete is increased with the addition of steel fiber and constant percentage of polymer.

Abstract

Groundwater management is very necessary due to scarcity of surface water sources and has heavy stress on its utilization for different purposes. Contamination of water either on surface or in ground is crucial problem. Now days various models are developed to assess groundwater quality. When the contaminant is subject to chemical constituent that follows a non-linear sorption isotherm, the resulting differential equation is non-linear. Analytical solution of non-linear differential equation is difficult. In present paper, main focuses have been made on sorption of contaminant species in groundwater. Finite difference models were developed to assess the groundwater quality for different sorption isotherms namely, Freundlich and Langmuir with linear and non linear conditions. Results of numerical model were compared with available analytical model. It is found that all results are comparable and matches approximately. A combined study for plumes behavior for sorption and no sorption situations has carried out for spatial and temporal variation. Such kind of study would be useful for finding contaminant species interactions with groundwater when it subject to sorption for wide range of field conditions with regard to dispersion and source definition.

Abstract

The phosphogypsum (factory.Over 6 million tons of PG is produced per annum in India and poses various environmental and storage problems. Out of these some quantities are utilized for of production of ammonium sulphate and few for other uses, there is accumulated stock of PG) is the industrial waste by-product produced in various industries like fertilizer industry, phosphate ore, phosphoric chemical more than 10 million metric tons of PG at various plant sites. This paper covers the literature review of effective and economical utilization of PG as building material in the various ways. The phosphate industry has been searching different ways of reducing the size of PG stacks. Researchers have also been seeking new application areas for PG use as studies have indicated that it would be more environmentally sound to use by-products rather than to dump them. In today' world, there is an ever increasing demand for construction due to population expansion and shortage of building materials. Utilization of industrial waste such as phosphogypsum not only solves environmental problems but also provides a new resource for construction industry.

Abstract

Steel fibers are now days commonly used in concrete as due to addition of these fibers considerable strength is achieved. Fiber reinforced concrete possesses desirable properties like high compressive strength, stiffness and durability under usual environmental condition. In the present work, experimental test are carried out on SBR and steel fiber reinforced concrete to calculate flexural strength on beam, spilt tensile strength on cylinder. Casting of the specimen is done in laboratory using different % of polymer(styrene butadiene rubber) with varying the hooked end steel fiber. It is observed that by changing the % steel fibers and SBR concrete a strong cement hydrate- aggregate bond is developed. Also micro cracks are bridged by the polymer film on membranes which prevent cracks propagation. As observed flexural and bond strength of concrete is increased with the addition of steel fiber and SBR.
