Abstract
The objective of this research is to compare the evaluation of performance damage levels under seismic forces by guideline of FEMA 356 and DPT.1303-57. Five and eight-story reinforced concrete building were structural models by using finite element program. The studied building is a common housing building in Chiang Mai. The structure is a beam-column system and not be designed for earthquake resistance. Both buildings have rectangular shaped building. The height of five and eight-story building are 14.95 and 25.75 meters respectively. The Linear dynamic procedure (LDP) utilized modal response spectrum analysis (RSA) was used this procedure was conducted for 3-Dimensional structure. Fixed support was used. The evaluation results indicated that performance level of both of the buildings is collapse prevention level (CP). The acceptance criteria of performance level for beam based on the guideline of DPT.1303-57 and FEMA 356 are slightly different, but, for a column, the both of guideline are different. The acceptance criteria of performance level for a column based on the guideline of DPT.1303-57, percentage of increasing was 0% - 20.70% for immediate occupancy Level (IO), and percentage of increasing was 0% - 20.40% for life safety level (LS) compared with guideline of FEMA 356. Whereas, the acceptance criteria of performance level for a column on CP level based on the guideline of DPT.1303-57, percentage of decreasing was 0% - 13.33% compared with guideline of FEMA 356.
