Steel Plate Reinforced Concrete Shear Walls

Reinforced concrete rc shear walls are used in high rise structures that can potentially be impacted by earthquakes.

Steel plate reinforced concrete shear walls.

The lateral resistance and deformation capacity of the shear wall are greatly improved. The reinforced concrete filled composite plate shear walls cpsw system employs two steel plates with infilled reinforced concrete. The design of rc shear walls with high lateral load capacity necessitates the formation of shear wall boundary zones with narrow cross section and intensive steel reinforcement because of the requirement for light weight walls to reduce seismic force and the architectural goal. A design of reinforced concrete shall be in accordance with csa a23 3.

From a designer s point of view steel plate walls have become a very attractive alternative to other steel systems or to replace reinforced concrete elevator cores and shear wall. Composite steel plate shear walls were first put into practice in a frame shear wall dual system of the bus station complex in nagoya japan in the early 1960s. B reinforcing steel placement shall conform to csa a23 1 csa a23 4 and or the local building code having jurisdiction. D minimum steel yield strength shall not be less than 300 mpa 40 ksi.

In comparative studies it has been shown that the overall costs of a building can be reduced significantly when considering the following advantages. C reinforcing steel bars shall conform to clause 7 of csa a23 1 and csa g30 18. A nonlinear 3 d finite element model in. Hanced steel plate reinforced concrete shear wall s j.

Wright per formance of double sk in pro fi led compo site shear. 119 2016 176 189. Graphical user interface is provided for. The steel plate wall acts as the web of the vertical plate girder and the column acts as the flanges of the vertical plate girder.

The composite shear walls discussed in this report consist of a steel plate shear wall with reinforced concrete walls attached to one side or both sides of the steel plate using mechanical connectors such as shear studs or bolts. Based on an experimental study of four flexural critical cpsw specimens under high axial compression ratio ranging from 0 313 to 0 542 and reciprocal lateral load the seismic performance of shear studs connected cpsw systems with orthogonal reinforcement in wall. It uses a graphical interface that enables the user to easily generate complex wall models. After the reinforced foundation finished the shear wall anker bolts should be installed into the foundation reinforcement before pouring concrete.

This paper investigates the deformation capacity of the sprc shear wall under cyclic loads. Astaneh asl 1998 2001 carried out a series of low frequency cyclic loading test on composite shear walls which consisted of a steel plate shear. In the aisc seismic provisions aisc 1997 these systems are denoted as composite steel plate shear walls c spw.
