[优化][编程] 基于SAP2000二次开发的平面桁架优化案例 (Optimization of plane truss structure through secondary development of SAP2000)

实干、实践、积累、思考、创新。 实际超高层工程案例中，外框常采用交叉支撑/交叉网格等形式加强外框刚度以形成强外框体系，例如深圳中信金融中心、深圳华润总部大厦、广州西塔等。为了初步探究交叉支撑点位置对外框刚度影响，基于简化平面模型以及SAP2000二次开发技术，采用枚举法对不同交叉点位置的桁架进行计算，以供参考。 1、平面桁架的简化模型 外框交叉支撑通常呈现疏密表现形式，简化模型通过可选交叉点位置大于交叉点道数模拟，各层水平荷载采用某项目指定风荷载。 表 平面桁架构件尺寸： 柱 方钢管2000X2000X100X100 梁/支撑 方钢管1200X800X60X60 2、SAP2000二次开发技术+简化模型 SAP2000的API功能是以程序语言的形式与SAP2000相结合,实现建模、分析、结果输入输出的智能化，它使得用户可以通过编译好的程序自动建立、分析模型并获得指定的分析和设计结果，用户可用另一种程序和SAP2000通过API接口相结合实现互动。本文通过SAP2000二次开发技术对所有枚举桁架方案进行内力分析，输出桁架顶点位移，以此作为整体刚度判定标准。 桁架交叉点位置变化视频 3、计算结果 基于简化模型和二次开发技术，将桁架顶点位移作为整体刚度判定标准，以下给出顶点位移从小至大的桁架方案结果 本文编者介绍 相关资料 ( Related Topics ) [01] [CSI OAPI][编程] CSI OAPI EX1: 运行/关闭/捕捉 SAP2000 [Start/Exit/GetActive SAP2000] [02] …

实干、实践、积累、思考、创新。 悬臂板配筋构造(有高差)，参考 图集 17G101-11。 （1）当悬臂板的跨度较大且板面与内跨标高一致时，由于悬臂支座处的负弯矩对内跨中有影响，当内跨跨度较小时，甚至会出现全跨均为负弯矩，因此上部钢筋应通长配置。板面有高差时应采用分离式配置上部受力钢筋，悬臂板上部受力钢筋在内跨应满足锚固长度的要求。 （2）无内跨纯悬臂板上部受力钢筋伸入支座内的锚固宜采用弯折锚固。当支座宽度满足直线锚固长度la时，上部受力钢筋宜伸至支座远端向下90°弯折，弯折段长度为15d;当支座尺寸不满足直线锚固要求时，水平段投影长度应不小于0.6lab，弯折段长度为15d。 （2）悬臂构件的上部纵向钢筋是受力钢筋，因此要保证其在构件中的设计位置，不可以随意加大保护层的厚度，否则造成板面开裂等质量事故。悬臂板要待混凝土达到100%设计强度后方可拆除下部支撑。 （3）抗震设防烈度为7度(015g)以上，且悬臂板跨度大于2米时，板上下纵向钢筋伸入支座内的锚固长度需满足抗震锚固要求。 相关话题 ( Related Topics) [01] [手绘大样][Detail Drawing] 墙竖向筋锚入基础 [Wall vertical ribs anchor into the foundation] [02] [手绘大样][Detail Drawing] 墙竖向筋锚入顶层板(梁) [Wall vertical reinforcement anchor into …
