Steel Plate Shear Wall

Experimental and numerical studies conducted in the past three decades have demonstrated that a steel plate shear wall is an effective and economical lateral load resisting system against both wind and earthquake forces. The system consists of infill steel plates connected to boundary beams and columns over the full height of the framed bay. The infill plates can be stiffened or unstiffened and the beam-to-column connections can be rigid or shear connections. A properly designed steel plate shear wall has superior ductility, high initial stiffness, stable hysteresis loops, and good energy absorption capacity. These characteristics make the system outstanding in high-risk seismic regions. Use of steel plate shear wall systems has been shown to be more cost effective than the other lateral load resisting systems. Steel plate shear walls are much lighter than the commonly used reinforced concrete shear walls, which reduce both the gravity loads and seismic forces. This aspect significantly reduces the foundation costs and makes the system outstanding for application in rehabilitation projects. Whereas construction cost of stiffened steel plate shear wall is more than unstiffened steel plate shear wall therefore in this investigation the unstiffened steel plate shear wall has been studied as two types of simple and corrugated plate and the behavior has been compared in one story frame. This study was conducted with finite element approach theoretically. The results of this study demonstrated that behavior of corrugated plate is superior to simple plate because it has high loading capacity, ductility and energy absorption.

The shear wall is a vertical structural element of a structural system that serves to withstand lateral loads, whether caused by wind or earthquake. In Indonesia is still often found structural system in old buildings that still use a minimal reinforcement ratio or in this case the lightly shear wall. The lightly sliding wall is believed to have a low lateral load capacity, but in some cases in many countries, the lightweight sliding wall is sufficiently resistant to earthquakes. The height-width ratio is an important aspect in the shear wall structure. Therefore, further research is needed on the effect of high-width ratios. This study discusses the effect of high-width ratios on shear lightly shear walls due to cyclic loads. In this study, the shear wall used as a test specimen with many test specimens was 9 shear wall walls with variations of height-width ratios (2.0, 1.3, and 1.0) or with sizes: (800x400mm), (800x600mm), and (800x800mm) . The test is carried out by providing cyclic load and axial load constant of 3% of axial capacity (Pn) of each specimen until the specimen is collapsed by the drift control method. Data in the form of loads and deviations per cycle are recorded for the analysis of collapse mechanisms. While the picture taken as a reference pattern of cracks. The results of the test show that with increasing height-width ratios can produce the smallest lateral load capacity, or vice versa. The lateral load capacity generated by each test object is SW 2.0 (1), SW 2.0 (2), SW 2.0 (3), SW 1.3 (1), SW 1.3 (2), SW 1.3 (3), SW 1.0 1), SW 1.0 (2), and SW 1.0 (3) are 1593kg, 1503 kg, 1592 kg, 3296 kg, 3388 kg, 3286 kg, 4772 kg, 4771 kg, and 4778 kg. Crack patterns that occur on each specimen have the same result that is the same occurrence of opening (gap opening) at the bottom of the wall.

Steel-Concrete composite shear wall has become popular recently as it compensates for the disadvantages of concrete and steel plate shear walls and combine the advantage of both. However, there is no detail study that identifies the most critical parameters. This study aims at investigation of steel plate-concrete composite shear wall behavior under cyclic loading with variables such as concrete strength, grade of steel plate, total number of tie constraints and thickness of steel plate. ABAQUS/Standard is used for numerical modeling in this study. As the concrete strength decreases from 86.1Mpa to 45Mpa, the load capacity declined by 11.76% and higher stiffness was recorded in specimen with higher grade of concrete. The ductility factor is inversely proportional to grade of concrete from 86.1Mpa to 60Mpa which increases from 4.26 to 4.68 and the ductility factor of specimen with 45Mpa strength is recorded as 3.81. The energy dissipation capacity is directly proportional to the grade of concrete used. Using high grade steel plate increases the lateral load capacity significantly and exhibited more ductile behavior. Specimen with S355 steel grade exhibited 14.01% increment of the average load capacity while the specimen with S245 steel grade has shown reduction by 9.21%. Similarly, the ductility factor and energy dissipation capacity of specimen with variable grade of steel are directly proportional. Reduction of tie constraints has no significant effect on the behavior in this study due to high confinement effect of concrete by surrounding steel plate. Specimens with thicker steel plate exhibited good energy dissipation capacity.

Steel Plate Shear Wall

Abstract Shear Plate Shear Wall (SPSW) is a lateral force resisting system that is usually used in high seismic regions. Opening can be accommodated by using coupled steel plate shear wall (CSPSW) where two or more SPSWs are placed adjacently and are connected by coupling beams. Maximum displacement, shear load capacity and energy dissipation are affected by the dimension of the coupling beams. The construction cost of the building can be reduced vastly by optimizing the size of the coupling beams where the capability of CSPSW to resist the earthquake is maximized. Thus, the objective of this study is to determine the behaviour of maximum displacement, shear load capacity and energy dissipation of the CSPSW when the width, depth and length of the coupling beams are varied. Fourteen CSPSW models were analysed by ABAQUS software, where the models were subjected to lateral cyclic loading as accordance to ATC24. Maximum displacement of the CSPSW was not affected by the dimensions of the coupling beams. Shear load capacity was increased as either the width or the depth of the coupling beam was increased, and achieved its maximum value when the length of the coupling beam was 1000 mm. The optimum width, depth and length of the coupling beam to maximize the energy dissipation of the CSPSW models were 200 mm, 1000 mm and 1000 mm, respectively.

Composite Shear

An RC shear wall (wall1), a composite shear wall composed of a single external steel plate connected to a concrete panel (wall2), a composite shear wall constructed from two external steel plates connected to an internal concrete panel (wall3) and finally a composite shear wall fabricated with a single internal steel plate embedded within a concrete panel (wall4) are considered in this study and their behavior are assessed and compared under the effect of an in-plane cyclic load. Variation of the three functions include shear load capacity, energy absorption and shear stiffness of the walls are evaluated numerically using the ABAQUS finite element software. The performance of numerical models is validated against to the experimental results. The effects of four parameters consisting of compressive strength of concrete, yield strength of steel plate, height-to-length ratio of the wall and the thickness of the steel plate are investigated on the above-mentioned functions. Obtained results show that the wall4 has the best performance among all four types of shear walls. For instance, the energy absorption capacity of the wall4 is approximately two times greater than that of wall1 and wall2.
