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.

Structure with replaceable devices is a type of earthquake resilient structure developed to restore the structure immediately after strong earthquakes. Current researches focus on one type of the replaceable device located in the structural part that is most likely to be damaged; however, plastic deformation would not be limited in a specific part but expand to other parts. To concentrate possible damage in shear wall structures, combined form of replaceable devices was introduced in this article. Based on previous studies, combined form of replaceable coupling beam and replaceable wall foot was used in a coupled shear wall. Influences of the dimension and location of the replaceable devices to the strength and stiffness of the shear wall were investigated through numerical modeling, which was verified by experimental data. Performance comparison between the shear walls with one type and combined form of replaceable devices and the conventional coupled shear wall was performed. In general, the shear wall with combined form of replaceable devices is shown to be better energy dissipated, and proper dimensions and locations of the replaceable devices should be determined.

Indonesia is one of the countries in the earthquake region. Therefore, it is necessary to build earthquake-resistant buildings to reduce the risk of material and life losses. Reinforced Concrete (RC) shear walls is one of effective structure element to resist earthquake forces. Applying RC shear wall can effectively reduce the displacement and story-drift of the structure. This research aims to study the effect of shear wall location in symmetric medium-rise building due to seismic loading. The symmetric medium rise-building is analyzed for earthquake force by considering two types of structural system. i.e. Frame system and Dual system. First model is open frame structural system and other three models are dual type structural system. The frame with shear walls at core and centrally placed at exterior frames showed significant reduction more than 80% lateral displacement at the top of structure.

The paper explores the failure mode, failure mechanism and deformation capacity of medium-high and low-rise shear walls. The experimental results from load-tests of 5 high-performance concrete shear walls with 1.5 and 1.0 shear span ratio indicate that the shear walls deformation capacity benefits from several bar rings like a chain along boundary element in plastic hinge zone, showing that shear wall deformation capacity design is reliable to a certain extent, in that the plastic hinge zone often influences the damage level of shear walls. With the damage at different stages, the paper divides the performance of shear wall structure into three kinds: serviceability, life-safety and collapse-prevention. Accordingly, it is proposed that the performance controlling indicators for shear wall structures is composed of storey drift ratio and the rotation of plastic hinge zone, and also provides consult values for each performance level.

This paper describes an investigation of coupled non-linear shear walls subjected to lateral load increasing monotonically up to overall collapse. Overall collapse includes base hinges in walls as well as yielding of connecting elements over either all or some portion of the total height. Curves useful for preliminary assessment of potential seismic performance of a structural system are generated following a parametric scheme. Particular attention is focused on connecting beam as well as system ductility capacities required to achieve overall collapse.

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 Continuum

To understand the higher modal effect on the accuracy of pushover analysis for shear wall structure, the influence of damage on the vibration characteristics of shear-wall structures is investigated. Employing the continuum technique, the shift of modal shapes and periods for the first three modes is obtained when the plastic zone exists in the bottom of the shear wall. It can be conclude that plastic zone may enhance the higher modal effect when the internal force responses of shear walls are considered. The higher modal contribution can not be neglected when computing the nonlinear earthquake responses of shear wall structures.
