Charts for Seismic Design of Frame‐Wall Systems
Publication: Journal of Structural Engineering
Volume 110, Issue 1
Abstract
Charts are presented for the seismic design by the response spectrum method of fixed‐base multistory buildings consisting of solid shear walls and frames, symmetrically arranged in plan and having constant properties along the height. The building is treated as a continuum with the frames modeled as a single shear beam, and the first three normal modes of the building are utilized for evaluating various modal responses, namely, the bending moments and the shear forces in the wall, the shear force in the frame and also the top deflection, the contribution of only the fundamental mode being considered for the last named response. The charts present the distributions of the modal moments and shears along the height of the building, which should allow the quantity of reinforcements to be varied for achieving economy. The results are presented for practical values of the nondimensional parameter which incorporates all the geometric and material properties governing the behavior of the system. The use of the design charts is illustrated by an example of a 15 story building.
