Finite element analysis of shear bearing capacity of 'T' joints of acromegaly steel slab shaped steel concrete special-shaped columns

摘要

The purpose of this study is to analyze the shear capacity of a steel slab shaped steel concrete column joint (SRC node for short). Compared with real abdominal SRC the advantage of the SRC is convenient for construction. It does not need to perforate the beam on the type steel and speed up the construction speed. In this paper, the finite element software ABAQUS is used to compare and analyze the shear capacity of the "T" - shaped joint of six - layer concrete - shaped column frame structure. The results show that the stress state and failure process of the SRC steel joints and the SRC joints are similar, and the shear capacity of the joints decreases, but the magnitude of the decrease is not large. It is shown that the SRC node of the open abdominal acromegaly steel sheet can meet the shear capacity and greatly improve the construction efficiency.
