<P>PROBLEM TO BE SOLVED: To provide a half precast type composite structural member capable of obtaining a structural member by taking into consideration even workability, by reducing member weight in construction, by rationalizing the design/construction of the structural member applicable to a place of a generating large cross-sectional force, and by obtaining the structural member having a small-scale cross section and having high rigidity and yield strength by a composite structure of steel and concrete. <P>SOLUTION: A half precast member 4 is manufactured by placing high performance concrete 3 having high compressive strength at a flange part of a steel member 2 such as H shape steel composed of a parallel flange and a web so that the flange part becomes a core material. The half precast type composite structural member 1 is formed by additionally placing infilling concrete 5 between the webs of the half precast members arranged in parallel. The high performance concrete is arranged on the compression edge of making maximum compressive stress act on an axial force and the bending moment, and the compressive stress is efficiently shared. <P>COPYRIGHT: (C)2008,JPO&INPIT |
