Fire resistance analysis of top and seat angles with double web angles connections
the paper establishes the top and seat angles with double web angles connections modal by FEA software. A heat-force coupling analysis with numerical calculation is discussed about this FEA model. The bearing capacity, thermal transmission and deformation of this modal are discussed under heat load and static load. The load transfer mechanism of the top and seat angles, webs, bolts in high temperature environment and the pre-tightening force loss of bolts due to temperature are analyzed thoroughly. Then the mechanics properties which are difficult to get only by texting are obtained by FEA analysis and the results can provide theoretical basis for the top and seat angles with double web angles connections about fire resistance, document.
