abstract

buildings with wall or frame-wall systems are more effective against earthquake forces and sustain less damage than buildings which their lateral resistance is solely depends on frames. four reinforced concrete (rc) structural wall specimens were subjected to cyclic loading using finite elements method with abaqus software in order to study influence of diagonal web reinforcement. the research parameters included the amount and configuration of reinforcing bars in the web. the conventionally reinforced wall failed due to web crashing with an abrupt drop in load capacity, whereas the walls reinforced with diagonal web reinforcement failed in a more ductile mode. the results clearly indicates that the diagonal web reinforcement increase the lateral load capacity of wall. the energy dissipation capacity of the diagonal web reinforced is superior to the conventionally reinforced wall.

Finite Element Analysis of Reinforced Concrete Column Under Lateral Load

To serve its purpose a structure must be safe against collapse and serviceable in use. Serviceability requires that deflections be adequately small to keep the cracks within tolerable limits. Although the widely followed ACI Code suggests a detailed method of deflection calculation, it often cannot exactly perceive the actual behavior of a structure. For this purpose, finite element analysis, u...

Finite Element Method for Static Cyclic Behavior of Steel Shear Wall with Corrugated Plates

The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...

بررسی تأثیر محصورشدگی بتن در رفتار غیرخطی دیوارهای برشی بتن‌آرمه بالدار

Flanged shear walls are used extensively in moderate- and high-rise buildings to resist lateral loads induced by earthquakes. The seismic performance of many buildings is, therefore, closely linked to the behavior of the reinforced concrete walls. They must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle failure under strong lateral lo...

Shear and Flexural Stiffnesses of Reinforced Concrete Shear Walls Subjected to Cyclic Loading

Seismic analyses of concrete structures under maximum-considered earthquakes require the use of reduced stiffness accounting for cracks and degraded materials. Structural walls, different to other flexural dominated components, are sensitive to both shear and flexural stiffness degradations. Adoption of the gross shear stiffness for walls in seismic analysis prevails particularly for the design...

Experimental Investigation on Cyclic Behavior of Butterfly-shaped Links Steel Plate Shear Walls

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 ...
