The steel plate shear wall (SPSW) with two-side connections can be arranged fl exibly in the structure, and has no additional infl uence on the column, but its buckling capacity is diffi cult to be deduced directly by thin plate theory. The low yield point SPSW (LYP-SPSW) with two-side connections is proposed in this paper, including unstiff ened LYP-SPSW, cross-stiff ened LYP-SPSW and diagonally-stiff ened LYP-SPSW. The elastic buckling performance and buckling capacity of these three types of LYP-SPSWs are studied by numerical simulation. On the basis of the accurate model, a series of parametric analysis on the key factors were conducted, including the height-to-thickness ratio, the stiff ness ratio of the stiff ener, and the stiff ness ratio of the edge member, which have eff ects on the elastic buckling stress of the LYP-SPSW with two-side connections. The elastic buckling stress of the SPSW can be eff ectively increased by adding stiff eners and edge members, but it is unnecessary to use oversized stiff eners and edge members. Based on a large amount of parametric analysis, simplifi ed formulas for calculating the elastic buckling stresses of the three types of LYP-SPSWs mentioned above are proposed in this paper.

Parametric analysis on the hysteresis performance of the low yield point steel plate sheer wall (LYP SPSW) with three different stiff ening confi gurations, including unstiff ened, cross stiff ened and diagonal stiff ened, was conducted using the fi nite element models which have been verifi ed by the test results. The parameters which have eff ects on the hysteretic behavior of LYP SPSW include ratio of height-to-thickness, stiff ness ratio of stiff ener, and the stiff ness ratio of the edge member. The hysteretic curves, skeleton curves and viscous damping coeffi cient-displacement curves of SPSW with diff erent stiff ening confi gurations were obtained. According to the numerical results, it can be seen that the shear resistance and hysteretic performance of LYP SPSW decrease with the increase of the ratio of height-to-thickness. The energy dissipation capacity and shear capacity of LYP SPSW can be improved eff ectively by setting cross and diagonal stiff eners, but when the stiff - ness ratio of stiff ener is greater than 10, the increase is no longer obvious. Furthermore, for steel plate shear walls without edge members, the diagonal cross-stiff ening steel shear wall can achieve better energy consumption. For steel plate shear walls with edge members, when the ratio of height-to-thickness is less than 100, a better energy dissipation can be achieved by using cross stiff ened steel plates; when the ratio of height-to-thickness is greater than or equal to 200, a better energy dissipation can be refl ected by adopting cross stiff ened steel plates. Finally, a restoring force model of the LYP SPSW with two-side connections is proposed.

Direct Strength Method for Stainless Steel Lipped Channel Columns Undergoing Local Buckling
Meihe Chen,Shenggang Fan,Chenxu Li,Shaoru Zeng 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.6
This paper reports the results of a numerical investigation on the influence of local buckling on the ultimate strength and design of locally fixed-end and globally pined-end stainless steel lipped channel columns in compression. The elastic buckling load is a key parameter in predicting the design strength of stainless steel lipped channel columns. Elastic buckling loads under simple–simple, clamped–clamped and experimental boundary conditions have been compared. To extend the data, a finite element model of stainless steel lipped channel columns has been developed and verified against the test data. Parametric studies on the stainless steel lipped channel columns were performed. The test results are compared with the strength predictions from direct strength method (DSM), indicating that DSM included in North American specification is unsafe, but the DSM proposed by Becque et al. is conservative. A modified DSM equation was proposed and has been proven to accurately predict the ultimate capacities of the stainless steel lipped channel columns in compression
