ANALYTICAL STUDY ON REINFORCED CONCRETE BARBELL SHEAR WALLS
Mahmoud Ahmed Sayed Saeed;
Abstract
Summary:
Behavior of reinforced concrete barbell shear walls is investigated in this
research. The output of the finite element program ANSYS are validated using
experimental results. The shear wall specimens were analyzed for different
parameters. The results from validation were used as inputs for studying the
effect of enlargement ratio, confining end region of shear walls, ratio of vertical
loads and the effect of increasing the thickness and width of enlargement on
performance of shear wall for resisting lateral forces. It was concluded that for
the optimum seismic performance, width of enlargement should not exceed the
length of compression zone and vertical loads ratio should not exceed 10 % of
gross area of shear walls. It was found that the thickness of enlargement has no
effect if it exceeds (1/10) of the unsupported height and confining of
enlargement has an important effect on strain of the compression zone.
