“…Under earthquake loading, the joint will be the most critical area to resist the lateral seismic reaction forces (Suyamburaja and Subramanian, 2008). Its characteristics affect the global behavior of the whole structure, particularly when subjected to seismic loading (Ebrahimi et al, 2010). Therefore, the strength of the joint has to be higher than the strength of the member it joins.…”

Problem statement: Despite demonstrating rather much benefits comparing to the conventional cast-in-place construction, the acceptance level of precast concrete building is still reportedly low in Malaysia. The implication imposed by stricter seismic design provisions would only worsen the matter. Approach: The main objective of this study was to identify the most appropriate type of beam-column connections to be introduced to precast concrete industry, particularly for regions of low to moderate seismicity. Hence, this study presented a comprehensive literature overview of the findings from studies conducted to analyze and investigate the behavior of precast concrete systems assembled with typical connections or joints under simulated earthquake loading. Results: The seismic performance of precast concrete structure very much depended on the ductility capacity of the connectors jointing each precast components, especially at critical joints such as the beam-to-column connections. It was learnt from the review that (1) hybrid post-tensioned beam-column connection and (2) Dywidag Ductile Connector® were among the most widely used connectors for precast construction in seismic prone regions. Conclusion: Future refinement and research could be carried out in order to optimize these connections to be used in low seismicity regions. Proposed connection type should be practical and well-accepted to avoid further impediment of the precast system.

Precast construction is gaining importance during recent past. Most of the studies reported on precast beam-column joints are to select the appropriate connections to be adopted particularly for regions of low to moderate seismicity. This paper reports on a comprehensive review of literature on the investigations carried out to analyze and evaluate the behaviour of precast concrete structural systems assembled with typical connections or joints under simulated earthquake loading. The seismic performance of precast concrete structure very much depends on the ductility of the joints framed by precast beams and columns. It has been understood that (1) moment resistance beam-column connection and (2) ductile connectors seems to be the most widely used in the precast construction in seismic regions. Further, refinement and research could be carried out in order to optimize such connections to be recommended in low seismicity regions.

“…Since the 1994 Northridge earthquake, a significant amount of research has been conducted and papers have been published (Fema, 2000;Sherbourne and Bahaari, 2000;Sumner, 2003;Adany and Dunai, 2004;Maggie et al, 2005;Shi et al, 2007;2008;Yanga et al, 2009;Lamom et al, 2010;Ebrahimi et al, 2010), participating in positive design modifications to improve the behavior of beam-to-column steel connections. Sherbourne and Bahaari 2000developed three-dimensional finite element models to study the behavior of eight-bolt large capacity extended endplate steel connections.…”

Problem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology elements instead of legacy elements which were previously used by other researchers. Approach: A finite element software package (ANSYS, version 11.0) was used to create and analyze three finite element models. Two of the finite element models were compared with previously reported experimental results to validate the accuracy of the finite element models. The third model was based on a modification of the second finite element model to improve bolt force distribution. Eight-node brick solid elements were used to model the connection members. The bolt shank was modeled using one three-dimensional spar element that connected the bolt head and nut together. Pretension in bolts, contact algorithm and material nonlinearity were considered in the finite element models. Results: Results of the first and the second finite element models were compared with experimental data. The comparison was based on moment-beam rotation and moment-endplate separation of the finite element models and the corresponding tested specimens. The results of the finite element models were used to compare the behavior of the bolts in the tension region adjacent to the beam bottom flange. Conclusion: The comparison showed good correlations between the finite element models and the corresponding tested specimens which confirmed the validity of the proposed models. Thus, a modified connection was proposed to improve the connection response. A finite element model of the modified connection was modeled, analyzed and compared to the original finite element model prior to modification to show their correlation
