COMPUTER AIDED DESIGN OF PRECAST REINFORCED CONCRETE ROOFING ELEMENTS

Abstract

To meet the housing shortage in the country within a reasonable timeframe prefabrication of the full structure or some major components seems to be the only answer. Adoption of prefabrication leads to a product with a better strength and quality. The materials are efficiently utilised and enormous time and money is saved. Moreover the grand success can be achieved by adopting the prefabrication technology at places of adverse climatic and weather conditions like subzero temperature, inclement weather in rainy season and deserts. In the cases when the time period is the most critical factor then adoption of prefabrication technique becomes the only alternative. This dissertation work consists of the development of software package for the design of Precast Reinforced Concrete Roofing Elements (Channel and Double T-Sections) conforming to IS: 456-1978 requirements. The computer programs are written in FORTRAN and developed and implemented on PC-XT and. AT. The design ,program is quite general. It caters for the loads as per IS:875(Part 2)-1987. However, the program is capable of - designing for any other 'uniformly distributed load intensity also and thus floor units can be designed by using the same package. The drafting program derives its input from the design program. For drafting PLOT88 drafting package has been used. The usage of this package will not only increase the productivity and improve the quality of work but the designer also will be relieved from the repetitive and labourious design routine.
