Comparison of Structural Design for Earthquake Resistant of Commercial Building Using Column and Beam Structure following Building Control Act B.E.2566 and ASCE 7-16

Abstract

This article presents a comparative study on the structural design for earthquake resistance of commercial building using column and beam structures following Building Control Act, B.E.2566 and ASCE 7-16. The study examines the effects of live loads specified in Building Control Act, B.E.2566 in conjunction with seismic acceleration values from Building Control Act, B.E.2564 for a building located in Mueang District, Chiang Mai Province. The results indicate that when using load combination factors from ASCE 7-16, the design of structural columns requires a greater amount of main reinforcement and shear reinforcement in certain columns compared to those designed using the load combination factors from Building Control Act, B.E.2566. This difference is primarily influenced by load combinations where seismic forces dominate. Similarly, in beam design, the use of ASCE 7-16 load combination factors results in higher amounts of both main reinforcement and shear reinforcement in certain beams compared to Building Control Act, B.E.2566 Furthermore, it was found that reducing the dead load through the use of lightweight materials and modifying the live load based on the building type, as specified in the Ministerial Regulation, can contribute to a reduction in the required reinforcement in both columns and beams.
