摘　　要：近年我国钢筋混凝土现浇框架-剪力墙结构中,由于钢筋构造不当,偏差超出规范规定的情况经常发生,影响了结构受力和工程验收。主要问题有:主筋偏位、框架柱接头设计不当、框架纵向钢筋变径频繁、井式梁按主次梁绑扎、梁吊筋绑扎混乱、以膨胀螺栓代替同直径Ⅱ级钢筋等。对此进行治理时,一是设计者要把设计意图交代清楚,施工图有足够深度,节点有大样,交底详细;二是施工人员要熟知结构理论,不断丰富施工经验,具备严谨的施工作风。Recently in China,in cast-in-situ frame-share wall structure,poor arrangement of steel occurred very often.The deviation exceeded national standard which affected structural test.The major problems include main steel off position,improper design of frame joint,too frequent diameter change of vertical steel,disordered hanging steel of beams and grade II steel being replaced with expansion bolt.When remedying,the designer shall expressly describe his purpose,providing working drawings with adequate details,while site technicians shall have good commend of structural knowledge and keep cumulating construction experience.
