Modeling of two-storey precast building under past earthquake records using Dynaplot program

Precast technology is not a new technology been implemented in construction industries in Malaysia since it has been introduced as early as 1960’s. Current practice in Malaysia, design of precast reinforced concrete building was made in accordance to British Standard code of practice for structural use of concrete in buildings and structures, where it has no specific provision on seismic design. Ranau earthquake with 5.9 Scale Richter which happened in June 2015 had caused major tremors and severe damages towards reinforced concrete buildings which have been designed with current code of practice. In this paper, a two story precast school building which has been designed as moment resistance frame using the current code of practice was selected as the prototype building. The selected prototype building has been modeled and analyzed by using Ruaumoko 2D and Dynaplot program to obtain maximum lateral displacement and to assess the structural deformation of the precast building at peak ground acceleration for selected past earthquake history. The results exhibited that the maximum displacement recorded at 125.40 mm when subjected to El-Centro East-West Earthquake. The precast building also will experience severe damage at beam-column joint that will lead to the collapse of building at PGA of 0.348g.
