Steel Plate Shear Walls (SPSW) consist of unstiffened infill steel panels surrounded by columns, called Vertical Boundary Elements (VBE), on both sides, and beams, called Horizontal Boundary Elements (HBE), above and below. These infill steel panels are allowed to buckle in shear and subsequently form a diagonal tension field. SPSW are progressively being used as the primary lateral force resis...
Conventional design of steel plate shear walls SPSWs assumes that 100% of the story shear is resisted by each infill panel. Following this approach, strength provided by the boundary frame moment resisting action, which provides the SPSW with overstrength, is neglected. While this design assumption has a positive impact on seismic performance of SPSWs, no analytical work has been done to quanti...
A new conceptual non-thermal anti-icing system for helicopter rotor blades is introduced. Theoretical calculations predict that certain ultrasonic modes generated by horizontal shear waves produce sufficient interface stresses between a host structure and ice to remove the accreted ice layer. Experimentally obtained ultrasonic shear dispersion curves are compared to theoretical predictions for ...
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 ...
Abstract During the last three decades, interest in application of steel shear walls has increased worldwide. Steel are used as stiffened and unstiffened walls. One main shortcomings plate wall (SPSW) is infill buckling mainly under lateral wind seismic loads. useful solutions to prevent use with corrugated plates. In this research, behavior a consisting two plates was investigated material cas...
The concept of spraying thick layer of polymer material onto metal plate has recently received considerable interest in many civilian and military applications. There are numerous analytical and numerical solutions for single thin plates (membrane) made of either a steel or an elastomer. However, solutions for composite plate made of both of the above constituents are lacking. The objective of ...
BACKGROUND A biomechanical study of three sternotomy closure techniques (figure-of-eight stainless-steel wires, Pectofix Dynamic Sternal Fixation [DSF] stainless-steel plates, and figure-of-eight stainless-steel cables) was conducted to compare strength and stiffness variables in three clinically relevant loading modes (anterior-posterior shear, longitudinal shear, and lateral distraction). M...
