A new partially bonded beam element for analysis of shear walls

AbstractA finite element formulation for multi‐panel shear walls based on a partially bonded beam system has been proposed. Idealization of a shear wall by a partially bonded multi‐layered beam element reduces the storage and computer time considerably. The finite element model has been employed extensively for parametric study of prefabricated shear walls of different widths and heights. Different numbers of in‐situ joints in the prefabricated shear wall assembly with varying shear stiffness of joints have also been considered. The parametric study gave an insight to the structural response of the wall system. Based on the non‐linear shear stiffness characteristic of in‐situ joints determined experimentally, the nonliner behaviour of a prefabricated shear wall has been determined and the failure load has been predicted.

Structural Behavior of Wood Shear Wall Assemblies

The paper is a summary of the results of an experimental program conducted at the University of Texas to investigate the structural behavior of 7 shear wall assemblies used in manufactured housing. Variables studied include the size and location of the shear wall within the assembly, the number of glued sides of hardwood paneling, and the number of floor joists beneath the shear wall. It was found that walls located on the windward side of the assembly had higher ultimate strengths. In addition, measurements of slip between the shear wall and side walls indicate that there may be significant load transfer into the side wall. Also, the side walls, it was found, do not provide rigid vertical support to the joists beneath the shear wall, as currently assumed in design.

Frequency analysis of coupled shear wall assemblies

AbstractThe finite strip procedure is used to predict the free vibration response of both planar and non‐planar coupled shear wall assemblies. The solid walls are considered as vertical cantilever strips and a comparison is made between modelling the spandrel beams as discrete beams and as an equivalent continuum with orthotropic plate properties. It is shown that both approaches lead to essentially the same frequencies. The effects of vertical inertial forces and shear deflection are included, and structures considered may have properties that vary with height. The method presented appears to be more versatile than previously published techniques and numerical comparisons with existing methods indicate the predicted results to be accurate.

Reinforced Concrete Shear Wall Assemblies

Further results of investigation of one-story and two-story reinforced concrete shear wall assemblies of precast elements, conducted between 1951 and 1956 at Stanford Univ, California; all assemblies were tested in specially designed shear jig; three individual diaphragms were tested in 200,000-lb testing machine.

Reinforced Concrete Shear Wall Assemblies

This paper gives the results of an investigation of one-story and two-story reinforced concrete shear wall assemblies. Tests were made on four one-story models with parallel shear walls connected by a reinforced concrete diaphragm. Loads were applied to the diaphragm, and three separate diaphragm tests were then made. Following these tests, two one-story specimens with face walls were tested. Finally, two two-story models were tested. Theoretical studies were made for all tests and practical design approximations are suggested.
