Editor's Note

摘要

Papers appearing in this issue of the Journal are selected from the following themes: metal structures, reinforced concrete structures, wood structures, dynamic effects, and wind effects. The issue concludes with two technical notes-one dealing with the application of active control techniques in optimal design of passive devices and the second concerning the behavior of OSB-sheathed wood shear panels with and without openings.rnA two-part paper by Vian et al. examines the behavior of "Special Perforated Steel Plate Shear Walls with Reduced Beam Section Anchor Beams." This paper presents results of an experimental investigation of specially detailed ductile perforated steel plate shear walls (SPSWs) designed to accommodate utility passage, and having anchor beams with Reduced Beam Sections connections. In the first part, findings from an experimental study on single-story, single-bay specially detailed ductile perforated steel plate shear wall (SPSW) frames are presented. The tested specimens included low yield strength (LYS) steel infill panels and also incorporated allowances for penetration of the panel by utilities. Though all specimens resisted the imposed input history of increasing displacements to a minimum drift of 3%, the perforated panel reduced the elastic stiffness and overall strength of the specimen by 15% as compared with the solid panel specimen. In the follow-on paper, finite element (FE) models of full SPSWs and sub-element strips are developed using ABAQUS to facilitate a comparison with experimental results and to investigate the influence of localized distribution of panel stress and strain between perforations. Based on the analytical and experimental results, recommendations for the design of these special detailed perforated SPSWs are proposed.
