Multi-Vertical-Bar Element Model for the Study of Axial Restoring Force in RC Shear Wall
نویسندگان
چکیده
Using the formula of shear bearing force of oblique cross section in eccentrically loaded column, we analyze the stress acting on short-leg shear wall and conventional eccentrically loaded column. We propose the formula for calculating the shear bearing force of oblique cross section of short-leg shear wall that considers the action of vertical reinforcing steel bars, flange and axial compression. Parameter fitting is done using the experimental data. To address the defects in the existing axial restoring force model of tensile/compressive bars, we establish the axial restoring force model for the edge bar under tensile and compressive loading until ultimate failure based on measured data. Thus a mathematical tool is provided for solving the axial restoring force in RC shear wall.

A Macro-model for Nonlinear Analysis of 3D Reinforced Concrete Shear Walls
Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...

متن کاملA Simple Approach to Predict the Shear Capacity and Failure Mode of Fix-ended Reinforced Concrete Deep Beams based on Experimental Study
Reinforced Concrete (RC) deep beams are commonly used in structural design to transfer vertical loads when there is a vertical discontinuity in the load path. Due to their deep geometry, the force distribution within the RC deep beams is very different than the RC shallow beams. There are some strut and tie model (STM) already been developed for RC deep beams. However, most of these models are ...

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...

Abstract: Reinforced concrete shear walls have been used throughout the world as known resisting elements for the lateral wind and earthquake loads. They are mostly designed and constructed based on elastic calculations and therefore resulting in un-economical sections. In order to overcome this weakness, scientists have proposed different methodologies to account for the non linear behavior of...
