Abstract:
Mutual obstruction of steel bar, hooked steel bar anchorage and perforation on steel skeleton are seldom considered during design of steel bar for rigid reinforced concrete. An engineering project is taken for example to make suggestions for determination of diameter of steel bar perforating hole, position of steel column hooped reinforcement hole, position of beam reinforcement hole of steel column, position of hooped reinforcement hole and draw hook hole of steel beam and position of longitudinal column reinforcement hole of steel beam.
