Abstract | Due to the advantages of high quality control, reduction in site formwork and site labor, and increased speed of construction; the use of precast is increasing in Bangkok. The precast structures are weak in their joint. They have performed poorly in past earthquakes. Bangkok lies in a zone of low to moderate seismicity. The precast frame shophouse in Bangkok are designed to resist gravity loads only. Because of weak joint and negligent lateral resistant design, these buildings might not have enough lateral strength and might collapse creating loss of life if an earthquake strikes. Hence in this study, the seismic response of a typical low rise precast concrete frame shophouse in Bangkok constructed with two types of welded splice type beam-column connections prevalent in Thailand was determined by non-linear time history analysis in PERFORM 3D. A monolithic building was also analyzed as a control specimen. To represent the behavior of the beam column connections, a joint element was incorporated into the analysis model. The joint element accounted for shear deformation. A set of 18 ground motions that characterize the earthquakes prevalent in Bangkok were used in the analysis. The seismic response of the precast concrete frame shophouse with welded splice type beam column connections was found to be comparable to similar concrete frame shophouse with monolithic connections in terms of drift demands, damage pattern in the building, joint shear deformation demands, column hinge rotation and beam hinge rotation. The precast concrete frame shophouses were found to be within life safety performance level/acceptance criteria. |
