Abstract

This is an investigation of the seismic response on the precast structure due to the beam to connection behaviour. Seismic could damage the whole building if it is not properly designed, especially in high seismic region. Connection is one of the crucial elements to limit building damage. A lot of research has been done on monolithic reinforced concrete building but lack of information on the behaviour of precast connection under seismic effect for the whole structure. This research methodology mainly consists of two parts. The first part is finite element static load analysis and the second part is frame seismic load analysis. Finite element static load analysis models 4 types of connection. Three of the connection verified against the experimental result which carried out by P.L Chan (2006). A new connection is created and model. For frame analysis, 3 storey and 21 storey with three type connections stiffness frames are loaded with static load and seismic load. Three types of connection stiffness are pinned connection, new connection and fixed connection. The stiffness of the new connection is obtained from the slope of the total load versus deflection graph in the elastic range. The seismic load is Elcentro earthquake and modified with 0.15g and 0.50g load intensity. From the analysis results, new connection plate with 10mm thickness and Bolt 22 mm diameter has sufficient stiffness, strength and more importantly it has higher ductility. Meanwhile, the frame analysis results show that the new connection behaves as semi rigid connection after compare with pinned connection and fixed connection.
