Damage Analysis of Industrial Steel-Building Structures Subjected to Potential Earthquake in the Northeast of Thailand
Keywords:
Pushover analysis, Steel structures, Seismic damage assessmentAbstract
This paper outlines an evaluation of industrial steel-building structures located in the Northeast of Thailand for potential seismic damage. Nonlinear static analyses were performed using plastic hinge model according to ASCE41-17 standard. This study focused on two levels of earthquakes i.e., at the level of design basis earthquake and the level of basic safety earthquake. Reference was made to the maximum considered earthquake in the Northeast of Thailand guided by both DPT-1301/1302-61 standard and recent results by Foytong et al. The results show that behavior of the steel-building structures depends on load distribution and initial axial load ratio of the steel columns. The steel column may experience small structural damage. However, there are no adverse effects on performance of the studied buildings at the immediate occupancy level.
