ABSTRACT: Purpose
of present work is to develop a reliable and simple method for structural
analysis of RC Shear Walls. The shear wall is simulated by a truss model as the
bar of a truss is the simplest finite element. An iterative method is used.
Initially, there are only concrete bars. Repeated structural analyses are
performed. After each structural analysis, every concrete bar exceeding tensile
strength is replaced by a steel bar. For every concrete bar exceeding compressive
strength, first its section area is increased. If this is not enough, a steel
bar is placed at the side of it. For every steel bar exceeding tensile or
compressive strength, its section area is increased. After the end of every
structural analysis, if all concrete and steel bars fall within tensile and
compressive strengths, the output data are written and the analysis is
terminated. Otherwise, the structural analysis is repeated. As all the
necessary conditions (static, elastic, linearized geometric) are satisfied and
the stresses of ALL concrete and steel bars fall within the tensile and
compressive strengths, the results are acceptable. Usually, the proposed method
exhibits a fast convergence in 4 - 5 repeats of structural analysis of the RC
Shear Wall.
