| Abstract | More reinforcement than required for strength is one source of overstrength. The increasing
reinforcement ratio has effect on increasing structural stiffness. Therefore, the reinforced
concrete shear wall frame structure with various reinforcement ratios in members was
determined through nonlinear time history analysis. The using one earthquake ground motion
is applied for both directions (X and Y direction) simultaneously. This building is of twenty
stories above ground level and three basements. There are seven cases which are normalreinforcement
ratio, low and high reinforcement ratio in shear walls cases, low and high
reinforcement ratio in beams cases and low and high reinforcement ratio in columns cases are
analyzed. The performance of building is investigated in term of maximum roof
displacement, inter-story drift, maximum base shear, maximum base moment, flexural
deformation capacity and shears capacity in beams and column. Overall performance is
generally good. The drift is within the acceptable range, specified in the performance criteria.
For flexural responses, almost all the members are within the acceptable limits, except beams
and columns that are at top part of the building seem to be inadequate capacity. In addition, in
term of shear capacity, almost all of the members have sufficient shear strength, unless
beams that are at bottom part of the building and columns that are at the last floor of the
building seem to have insufficient in shear capacity. Finally, the results are slightly different
although the reinforcement ratio in structural components changes. |
