Experimental Investigation on Cyclic Behavior of Butterfly-shaped Links Steel Plate Shear Walls

Authors

Abstract:

An innovative type called "butterfly-shaped links steel plate shear wall (BLSPSW)" was proposed as a lateral load resisting system. In this novel system, by creating butterfly-shaped links in the four sides of the web plate, the lateral load resisting mechanism is not the development of a diagonal tension field on the web plate (similar to Conventional SPSWs), but the capacity of the system is determined by the shear strength of the links. Therefore, the geometric parameters of the link as initial design inputs affect predicting and controlling the stiffness and strength of the BLSPSW. Three experimental specimens were loaded to examine the behavior of the proposed system. The first one was the conventional steel plate shear wall (called SPSW-1), and two others prepared of the butterfly-shaped link steel plate shear wall (BLSPSW) with links that have been controlled by shear yield (SPSW-BL 80) and flexural yield (SPSW-BL 130). The experimental results showed that the stiffness and strength of the BLSPSW specimens can be controlled by the link geometry. Also, the BLSPSWs indicated desirable ductility up to 10 percent and high energy dissipation, even in small drifts compared to the SPSW-1. At last, the shear strength formulation of the butterfly fuses was used to determine the shear capacity of the BLSPSWs and compared with the experimental results.

Experimental Investigation of Light-Gauge Steel Plate Shear Walls

This paper describes the prototype design, specimen design, experimental setup, and experimental results of three light-gauge steel plate shear wall concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity, and emphasis is placed on minimizing their impact on the existing framing. Three single-story test spe...

Improving Cyclic Behavior of Steel Plate Shear Walls with Elliptical Perforations

In this paper, the effect of elliptical shape openings was numerically compared to the case when circular openings were used in the steel panel shear walls. At first, the finite element model in ABAQUS was calibrated by experimental results, obtained from previous studies. Then, three steel shear panels with different sizes of elliptical openings were analyzed under cyclic loads, and the result...

Behavior of Vertical Boundary Elements in Steel Plate Shear Walls

The AISC Seismic Provisions and CSA S-16 Standard require a minimum moment of inertia for the vertical boundary elements (VBEs) in steel plate shear walls (SPSWs) to avoid undesirable VBE behaviors. The equation limiting VBE flexibility has been derived from a flexibility factor, ωt, developed in plate girder theory and the limit on VBE flexibility has been empirically specified based on previo...

Seismic Behavior of Intermediate Beams in Steel Plate Shear Walls

This paper presents some preliminary results of an ongoing research whose objective is to investigate the seismic behavior of intermediate beams (i.e., the beams other than those at the roof and foundation levels) in multi-story steel plate shear walls (SPSWs). Of primary interest is the determination of the strength level needed to avoid the formation of in-span plastic hinges, a relevant prac...
