| 总结: | The connections between precast concrete components play an important role in determining the stabilization of precast concrete framed structures. Despite numerous years of extensive research, no fully fixed design method exists. Many areas of connection behaviour still require investigation. Much of the research has been done, and approximate analytical methods are available for almost all the identifiable regular forms of tall structure. The main objective of this research is to investigate the moment of resistance and the behaviour of simple beam-to-column connections in precast concrete frames by using engineering software. This research methodology mainly consists of finite element static load analysis on braced and unbraced frame which with different connection types. From the analysis result, although the braced structure with fixed connection type is apparently posed the less displacement than other type of model in this analysis, but the value of displacement still not satisfied as a structural to resist all lateral especially seismic forces. Several unsatisfactorily connections, however, still show potentials of reaching the required loading capacity. Therefore, modification and improvement can be made to improve their performances. |
