Analysis of Finite Element on Precast Concrete Diaphragms and Their Connections under Seismic Loading

Abstract

The precast concrete buildings structures are high superiority and speedy construction with the assurance of durability. In addition there would be a reduction in site labor, formwork and possible damage during earthquake. Probably due to lack of understanding of the basic 'nature of precast concrete during earthquake these could not get a place in India till recent past. In fact with available tools and design philosophies designer of precast concrete structures can create a structure which will not only survive an earthquake but will be subjected to a very little, if any, damage. Desirable for this is the expertise and limit of tolerance in construction practice.the performance of precast concrete systems depends on the behaviour of connections. In low seismic region where gravity loads govern the design of structures, precast construction have been extensively used because it is assumed that minor discontinuities in the structures do not cause any problems hence less attention is paid to the connection details. But, in high seismic region, the connections between precast elements require special attention..this research is focus on the role of diaphragm and their connections for precast concrete structures within the lateral force resisting system.
