Torsional Coupling of Core Walls in Tall Buildings

The mechanics of the structural action in torsion of the core walls in tall buildings is examined in this paper. The coupling effect of the floor beams on the separate walls is considered and a general solution to the resulting differential equation is derived. Expressions for the wall bending moments, the beam shear forces and the wall displacements are given. The correlation of this theory with published test values is examined. Graphs of numerical values are given and an example is calculated to illustrate the order of the effect of the wall coupling. Duncan Michael
