In order to quantitatively evaluate the shear-bearing capacity of shear connectors of square concrete filled steel tube (CFST), push-out tests on 14 square CFSTs with shear connectors have been carried out. Among the 14 CFSTs, there are 13 specimens with steel plate connectors and one specimen with steel bar connectors. The following factors are investigated to figure out their influences on th...

The economies of coastal communities around the Great Lakes have historically been dependent upon maritime transportation. Urban ports and waterways continue to accommodate expanding trade, growth of tourism, and recreational boating. Even in this challenging economic period, planned expansions in the iron-ore, slab-steel, low-sulfur coal, and nonferrous metals industries and growing tourism in...

In this paper, a new type of steel-concrete composite member, concrete-filled core steel tube with outer angle steel plank reinforced concrete stub column, is proposed and a series of nonlinear 3D(three-dimensional) full-range numerical calculations under axial compression are carried out, some important factors are analyzed, such as the strength of the concrete, the steel tube and the angle st...
