红土创新广场采用钢管混凝土斜交网格外框架+单向伸臂+混凝土核心筒结构体系。通过研究分析平面的各种角度相交网格的外框,得到外框柱网的主要性能;通过比较分析伸臂和带状桁架的布置对抗侧刚度的贡献,确定了伸臂和带状桁架的数量,以最优的布置达到良好的结构性能;针对在重力作用下斜柱引起的楼盖水平轴力,分析了楼面梁的最大拉力和压力,为楼面梁的设计提供依据;对重要的伸臂K形节点、立面斜柱交叉节点进行了精细的有限元计算分析,并提出了加强措施,保证了强节点弱构件;进行了结构动力弹塑性分析,定性地找出了结构的薄弱部位,并提出相应的加强措施。
Laterite innovation square steel tube concrete skewed grid frame + uniaxial + concrete core tube core structure system. By analyzing and analyzing the outer frame of intersecting grids at various angles of the plane, the main properties of the outer frame net are obtained. By comparing the contribution of the boom and the truss arrangement to the lateral stiffness, the relationship between the boom and the truss The optimal arrangement to achieve good structural performance; for the horizontal axis of the floor caused by the inclined column under the action of gravity, the maximum tensile force and pressure of the floor beam are analyzed to provide the basis for the design of the floor beam; Of the boom K-shaped node, the intersection of the inclined column and the elevation of the column carried out a detailed finite element analysis and proposed strengthening measures to ensure that the strong node weak components; structural dynamic elasto-plastic analysis of qualitatively identify the structure Weak parts, and put forward corresponding strengthening measures.
