ANALYSIS OF MULTI-STORY FORMWORK SUPPORTING SYSTEM BY DETECTION AND FEM
-
摘要: 多层模板支撑体系配置不合理、拆除不当将造成支撑倒塌事故及施工阶段楼板开裂现象的发生,结合现场检测,运用有限元分析方法建立混凝土多层模板支撑体系整体三维模型,明确支撑体系拆除时间及架设方式对楼板结构承载力的影响;提出不同结构形式下多层模板支撑体系的相关技术要点。为控制模板支撑体系安全、快速、高效运转提供科学依据,为建筑工程的安全施工提供有利的借鉴。Abstract: Collapses of supporting systems and cracking of the supported floors often happen during the period of construction because of unsuitable configuration and incorrect removal of supporting system.Combined with field detection,three-dimension model of multistory formwork support system was built by FEM,the model could reveal the effects of the removal time and building style of supporting system on the bearing capacity of structure,and propose the corresponding technique key points with different structural styles.The study provided the scientific guides for controlling the safety,high-speed cycling of supports system and the reference to safety of construction.
