EVALUATION OF IN-PLANE STIFFNESS OF DRYLY BUILT-UP STEEL FLOOR MADE OF FLAT AND CORRUGATED PLATE

Abstract

In-plane stiffness of dryly built-up steel floor made of flat and corrugated plate is evaluated with using theoretical formulation and physical test. They indicate, 1) dryly built-up floor alone can satisfy required stiffness; 2) it is difficult to satisfy required stiffness when the floor is connected to beam by self-drilling screw; and 3) stiffness of built-up steel floor can be estimated by theoretical formulation shown herein with the accuracy between 0.8 and 1.4 as the ratio of test result to the theoretical value.
