The demand for new building has been increased significantly, which can sustain loads whether lateral loads as well as gravity load. So far concrete has proven its reliability on most of structural system but it has a big drawback which is the slow construction rate. To eliminate this issue precast concrete has been introduced to the construction since it is prefabricated in the factory and then transferred to the construction site for assembly. The use of precast concrete systems offers several advantages such as speedy assembly, higher quality, lower project cost, better sustain, and enhanced occupational health and safety. The major concern in the precast concrete system is the rigidity of connections or joints. In this research a laboratory test was carried out on a precast concrete frame with post-tension joints (scaled prototype 1:5) which have been subjected to lateral cyclic loading. The beamto- column connected to each other by threaded rod and nuts. The investigation is to find out the natural frequency of the frame before the testing and after each cyclic loading, maximum sway of the frame to check the lateral stability and ductility. The precast system was found to be more ductile than the conventional subframe and the test yield all the characteristic of system failure at ultimate limit state of cyclic loadings. |
