Experimental Study of Partially Encased Composite Columns with Built-Up Steel Shapes in Fire

摘要：

A comprehensive study has been conducted to investigate the fire performance of the behavior and strength of a new type of partially encased composite columns made with thinwalled, welded H-section, stiffened with transverse links. The behavior of partially encased composite columns without fire protection subject to axial loads has been experimentally investigated and the results are presented in this paper. The influence of several parameters on the fire resistance is included, the load ratio and the section size. It was observed that during heating all specimens underwent concrete spalling at mid-height, which noticeably decreased the fire resistance.
