A Bidirectional B-Spline QR Method for the Analysis of Reinforced Concrete Shear-Wall with Opening

Abstract

In this paper, based on the bidirectional B-spline QR method (BB-sQRM), the mechanical properties of the shear-wall with opening were studied. The cubic B-spline function (CB-sF) was used to construct the basis function of the BB-sQRM for its good properties. The new computational scheme of the BB-sQRM for structural analysis was established with quadrilateral element. Numerical example was given to illustrate the validity of the proposed algorithm for the shear-wall with opening. The reliability of the proposed algorithm was verified by comparing with the results of ANSYS. The effects of the opening size on lateral displacement and stress of the shear-wall with opening were discussed. The numerical results show that, square hole and rectangular vertical hole are more conducive to bearing capacity of the shear-wall with opening.
