Based on the plane-section assumption, the formulas of yield moment and ultimate moment are derived for calculating high-rise RC shear wall. High-strength steels are used as transverse and longitudinal steels in boundary concealed columns of the shear wall. The practical application is performed by using the formulas derived for calculating horizontal bearing capacities of four specimens, in which one specimen used ordinary-strength steel and the others used high-strength steel. Meanwhile, the numerical simulation is carried out on the four specimens by finite element method, and the results show that the horizontal bearing capacity of the shear wall increases obviously for specimens using high-strength steel in boundary concealed column, and the simulation results of finite element method are in good agreement with formula results.

High-strength steel suffers from an increasing susceptibility to solidification cracking in welding due to increasing carbon equivalents. However, the cracking mechanism is not fully clear for a confidently completely crack-free welding process. To present a full, direct knowledge of fracture behavior in high-strength steel welding, a three-dimensional (3-D) modeling method is developed using the extended finite element method (XFEM). The XFEM model and fracture loads are linked with the full model and the output of the thermo-mechanical finite element method (TM-FEM), respectively. Solidification cracks in welds are predicted to initiate at the upper tip at the current cross-section, propagate upward to and then through the upper weld surface, thereby propagating the lower crack tip down to the bottom until the final failure. This behavior indicates that solidification cracking is preferred on the upper weld surface, which has higher weld stress introduced by thermal contraction and solidification shrinkage. The modeling results show good agreement with the solidification crack fractography and in situ observations. Further XFEM results show that the initial defects that exhibit higher susceptibility to solidification cracking are those that are vertical to the weld plate plane, open to the current cross-section and concentratedly distributed compared to tilted, closed and dispersedly distributed ones, respectively.

Compression behavior of a novel type of SiC/Al co-continuous composites was investigated using the finite element method and a new constitutive model were presented in this paper. The results show that the new constitutive model of the co-continuous composites can predicate the compression behavior of the composites accurately according to the simulative data. The fitting curve of the compression behavior achieved from the constitutive formula accords with the simulation results, which improves the reliability of the simulation on composites.
