There is a need of a good cooperation between the architects and structural experts for the creation of earthquake architecture. Through some ways in the design process, the architects can identify and evaluate the vulnerability of the building towards earthquakes. Unfortunately, there is no evaluation method available, so that the alternative is by adopting SVA (Simplified Vulnerability Analysis) method
which is the limited engineering analysis based on the information from the architecture and structure drawings on the existing buildings. The Japan Building Disaster Prevention Association (JBDPA) and Matsutaro Seki developed the SVA. Seki adopted the SVA of JBDPA and adjusted it with the international earthquake regulation. In principle, the JBDPA and Seki SVA is a safe structure if the seismic structure index ≥ the seismic demand index. The modification of the JBDPA dan Seki SVA in this research is that the
seismic structure index is the column dimension index, column rigidity index, strong column/weak beam index, redundancy index , and structure ductility index. Meanwhile, the seismic demand index is the multiplication between seismic response index and the priority factors of building functions. It is a quantitative research with experimental research method. The modified SVA formulation was xperimented through the pushover analysis from other researchers. The results were then tabulated and compared. In general, it is concluded that the modification on SVA formulation from JBDPA and Seki shows a relatively good result in evaluating the vulnerability of preliminary design of the structure in the architectural design process
