Since seismic design codes have complicated structures and comprise of various factors and formulas, they take an approach to compare actual structural designs for the same simple architectural designs based on the codes of the Philippines and Japan. They choose a simple design of RC structures of five stories without shear walls. They find that there exists a significant difference in story drift limit in the two codes. The rational design, based on strength alone, of a moment-resisting frame which meets requirements by load combination of the Philippine code does not satisfy the limit of story drift. Therefore, they try to reduce the story drift by increasing dimension of columns and beams, enlarging thickness of slabs and using concrete of high strength. A design which satisfies the story drift limit is compared with a design based on Japanese code. Pushover analysis is applied to three designs to analyze behavior focusing on the story drift. The analysis shows the story drift calculated based on the provisions of the Philippine code is far large than that by the pushover analysis. The authors conclude RC structures in the Philippines are recommended to have shear walls to rationally satisfy the story drift limit and the provisions in the Philippine code to calculate story drift for moment-resisting frames needs further discussion.
