Precast panel shear walls are investigated for conditions simulating progressive collapse. The latter are simulated by assuming ineffective panels at various levels within the structure. The analysis is performed by an efficient finite element substructuring procedure for both static and seismic loadings, and by a simple rigid-cantilever approximation for static loading only. The principal interest concerns the magnitude and distribution of design forces in vertical and transverse ties which, in the finite element analysis, are modelled by discrete connectors along horizontal and vertical joints. For static loading the results evaluate the accuracy of the simple cantilever design procedure, whereas for seismic loading the magnitude and distribution of connector forces resulting from local panel failure are examined. In particular, it is shown that failure of an exterior panel leads to unexpectedly large concentrations of shear force in the vertical joint, something that is not adequately predicted by the simplified cantilever analysis.

Seismic Behaviors

In this paper, a total of five structural insulated panel shear walls (SIPSW), in which with plywood facing and polystyrene foam board core, were tested under low cyclic horizontal loading. For the test specimens, different wall depth-width ratio and the opening sizes have been considered. The failure modes, failure mechanics, bearing capacity, lateral stiffness and ductility are discussed in detail. The test results showed that the hysteretic curve of SIPSW shows a reversed S-shape. Also the depth-to-width ratio and the opening dimensions of the shear walls have significant effects on load bearing capacity, ductility and elastic stiffness. What’s more, the performance of the SIPSW specimens was controlled by the fastener slip behavior of the SIP-to-spline connection, especially along the bottom spline. Finally, it is indicated that SIPSW have a good satisfaction upon seismic performance when used to timber structures.

Seismic Response Of Buildings

The roof framing in single-storey buildings with large foot prints, generally used for commercial, educational, or institutional purposes, often consists of a flexible steel deck or wood panel diaphragm. Resistance to seismic lateral loads is provided by steel bracings, masonry shear walls, concrete shear walls, wood panel shear walls, or cold formed wall systems. The response of such buildings to seismic loads is strongly affected by the flexibility of the roof diaphragm. Diaphragm flexibility alters the manner in which the inertia forces, shears, and bending moments are distributed along the length of the diaphragm. In addition, it causes a significant increase in the ductility demand on the lateral load resisting system that is expected to be strained into the inelastic range under the design earthquake. Results of a study on the linear and nonlinear seismic response of buildings with flexible diaphragms are presented.
