Effect Of Repeated Far Field Earthquake On The Ductility Demand Of Low-Rise Reinforced Concrete Buildings

Impacts of seismic activity on building should be considered seriously to provide a safe building. Earthquake phenomenon is not a single event but repeated phenomenon. However, current seismic design codes are ignored the effects of repeated earthquake. During the earthquake hits the ground, the factor that directly related to the damage of the structure is well known as ductility demand. The objective of this study is to determine the effect of repeated earthquake on the ductility demand of low-rise RC buildings. The nonlinear time history analysis performed to determine the ductility demand for two low rise building models which is 3 storey and 6 storey using RUAUMOKO software. There are 20 pairs of far field earthquake (FFE) randomly combined was used to performed 1800 analyses. Findings from this study showed that, the repeated earthquake give the increment 14.91% and 48.69% of ductility demands for 3 and 6 storey models, respectively. Meanwhile, force reduction factor also give the increment 113.39% and 40.49% of ductility demand for 3 and 6 storey models, respectively

Post Windstorm Evaluation of Critical Aspects Causing Damage to Rural Houses in the Northern Region of Peninsular Malaysia

Rural houses are susceptible to roof blown off and severe damage during a windstorm event due to the lack of engineering considerations. The aim of this paper is to conduct a post windstorm evaluation on the damaged rural houses located in the northern region of Peninsula Malaysia. Several activities were involved during the post windstorm survey including site visualization, site measurement and interview. Critical aspects including types of damages, types of houses, gap height, overhang length, roof geometry, roof pitch, roof cladding and terrain category were analysed using a simple bar chart. It is anticipated that the presence of kitchen house influences the overall stability of the rural houses due to the formation of gap height
