Summary: This study used finite element models to simulate the effects of different FSS levels and cell spacings or frequencies on the distribution of local wall FSS around cells. The results showed that an increase in cell spacing decreased the polarization of wall FSS distribution around cells, with frequency having minimal effect at low FSS levels and enhancing fluctuation at high FSS levels. These findings lay a foundation for further research on the flow-induced migration of osteoclast precursors and shed light on the mechanism of mechanical stimulation-induced bone resorption.

Summary: This paper investigates the elastic shear buckling behavior of trapezoidally corrugated wall plates in vertically or horizontally Corrugated Steel Plate Shear Walls (CoSPSWs) with constraints from neighboring subpanels and boundary frame members. The study finds that the constraints from boundary frame members along the corrugated edges have a significant influence on the shear buckling behavior, while the constraints along the straight edges have a negligible influence. Various factors such as plate thickness, straight edge length, corrugated edge length, inclined subpanel width, corrugation angle, and corrugation depth affect the global shear buckling stress of corrugated wall plates.

Summary: This study investigates the repair method of damaged steel plate shear wall in a steel frame. The test results show that replacing the damaged infilled plates increases the stiffness and improves the seismic performance of the specimen. The study also highlights the importance of investigating the plastic development of the boundary column to ensure reliable post-earthquake performance and easy repair of the steel plate shear wall.

Summary: The demand for large area parallel plate ionization chamber (PPIC) or large area ionization chamber (LAIC) has increased due to the advantages of a large effective area in monitoring therapeutic radiation beams. However, the heterogeneous responses of the large sensitive area pose a concern for the straightforward applications of PPICs in clinical dosimetry. This study presents a new systematic uniformity calibration method to improve the lateral response of PPIC and enable its practical application in routine clinical dosimetry.

Summary: A new type of foam-infilled corrugated FRP-steel sandwich shear wall is proposed to reduce the excessive out-of-plane buckling deformation of conventional steel plate shear walls. Experimental tests show that this structure can improve the initial stiffness, ultimate bearing capacity, cumulative energy dissipation, and reduce the maximum out-of-plane displacements of the steel plate under shear force.

Summary: This research focuses on the shear strength and post-peak behavior of trapezoidally corrugated wall plates in vertically or horizontally Corrugated Steel Plate Shear Walls (CoSPSWs) through nonlinear pushover analyses. Results showed that corrugated wall plates could develop a shear strength close to the shear yield strength at relatively low lateral drifts, and the lateral load-drift curves usually experienced a descending stage.

Summary: The performance of steel plate-wrapped concrete shear walls was studied, including hysteresis behavior, stiffness degradation, bearing capacity degradation, energy dissipation, cyclic ductility, and shear lag behavior. The test results showed that specimens with wide flange exhibited higher bearing capacity and initial stiffness, while specimens with narrow flange had better cyclic ductility and energy dissipation capacity.

Summary: A new type of steel plate shear wall with oval-curved architectural openings and vertically flexible horizontal connection elements is proposed, which can accommodate construction settlement and exhibit stable seismic behaviors. Finite element analysis and quasi-static cyclic loading tests have confirmed its effectiveness. The new design equations derived from integral and extreme value solutions accurately predict the mechanical behavior of this OVSPW.

Summary: This article examines the effects of wall shear stress on the flow of dusty viscoelastic fluid. The governing equation for fluid and dust particles is formulated as a set of partial differential equations. The perturbed solution is obtained using the Poincare-Lighthill perturbation technique (PLPT) and plotted using Mathcad-15 software. It is found that the increase of inclination angle controls the flow of fluid and dust particles.

Summary: A plastic design method for SPSW-RCF structures based on energy balance is proposed in this paper. The design parameters of SPSW and RC frame are determined by calculating the design lateral story shear forces using the energy balance principle. Nonlinear dynamic analysis and comparative study are conducted to obtain performance indicators under different structural parameters, while the SPSW-resisted story shear ratio is quantified.

Summary: This research presents an experimental test and finite element method to investigate the seismic performance and shear lag effect of T-shaped steel plate reinforced concrete composite shear walls (SPRCWs). The test results demonstrate that T-shaped specimens exhibit more satisfactory seismic behavior than rectangular specimens, with different failure modes depending on the shear span ratios. Smaller axial compression ratios and web lengths, as well as greater flange widths, result in better deformation capacity and energy dissipation capacity.

Summary: The buckling-restrained cold-formed steel plate shear wall (SPSW) is a new type of shear wall that integrates building and structural functions. Different buckling restraints can impact the cyclic shear performance of SPSW, with hat-section steel strips playing a key role in improving its bearing capacity. The design rule in AISC is the most conservative, while the design method of Eurocode 8 is the most accurate.
