The paper presents a system of programs for calculating stresses and displacements in three-dimensional shear wall structures with uniform properties throughout the height. The analysis is carried out on the basis of the continuous connection method. The system allows for considering lateral and vertical loads, arbitrarily located in the plan and arbitrarily distributed along the height. The system is user-oriented and inexpensive in operation. Two numerical examples are given in the paper.

A method has been proposed for the analysis of three‐dimensional shear wall and shear core assemblies having stepwise changes in the cross section. The analysis is based on a variant of the continuous connection method. In the continuous approach, the connecting beams are replaced by equivalent continuous connections. The differential equation systems for shear wall structure segments of constant cross section are uncoupled by orthogonal eigenvectors. The solution matches the boundary conditions of the upper and lower parts of the wall at the plane of contiguity, at which an abrupt change in cross section occurs. This yields a system of linear equations, which enable the determination of the integration constants. The correctness and efficiency of the proposed method are illustrated by its application to the analysis of plane and three‐dimensional shear wall systems of variable cross section.

The paper presents a continuum method for dynamic analysis of asymmetric tall buildings with uniform cross‐section in which the horizontal stiffness is provided by shear walls and columns of arbitrary shape and layout, coupled by horizontal beams. The equations of motions are formulated in variational terms, including axial strain energy. Numerical solutions, obtained by using finite time differences and infinite polynomials, are presented for the response of a twenty‐storey building with six shear walls to an impact load and earthquake accelerations. It is shown that omission of the axial deformations results in a substantially distorted pattern of behaviour, some of its effects being: Overestimation of the bending stiffness of the coupled shear walls, with corresponding changes in their stiffness ratios. Underestimation of the periods of the principal modes, with a corresponding change in the dynamic response. Distortion of the magnitude, form, time of onset and coupling of the maximum displacements. Pronounced change in the shear force and moment diagrams for the shear walls, the beams and the building as a whole.
