非弹性材料条件下施工期结构支撑体系荷载传递分析模型

施工期钢筋混凝土结构是时变结构,期间楼层承担的施工荷载随楼层位置和时间不断变化。本文在分析总结国内外研究成果的基础上,针对钢筋混凝土的不均质非弹性材料的特性,提出了更精确的施工期荷载传递结构模型和分析方法。并通过与前人实测数据和理论计算值进行比较,验证了其准确性和使用性。可为施工期结构安全分析和施工组织设计提供理论依据。

Analysis model of load distribution on time-dependent structure during construction period under the property of the unelastic material

Casting in-site concrete buildings during construction is time-dependent,The construction load bear by floor are changing with the position of floor and time.Based on the result of studies at home and abroad ,New structural model and analytical method which considers the property of the non-heterogeneous unelastic material of reinforced concrete.Comparising with other methods computated value and the date which got from experiment by people of past time,it Verify accuracy and possibility of this new medel. It can provide theories basis for controlling the sofety during construction and design of construct organization .
