【摘要】 为研究H型钢楔形构件的载常数,分析了现有H形楔形构件任意截面惯性矩的表达式,采用了一种精度高的新表达式。根据等效结点荷载的定义,推导了不同边界约束下H型钢楔形构件在各类荷载作用下的载常数解析表达式,运用Mathematica软件得到了简化公式。通过与基于Excel/VBA的SAP 2000/API的有限元分析结果比较表明,提出的简化公式形式简便、精度高,使用方便。更多还原

【Abstract】 For research on load constants of H-shaped tapered members,the characteristics of moment of inertia of Hshaped tapered members was analyzed and a new form which has high precision was selected. According to the definition of equivalent nodal load,the analytical expressions of load constants was deduced for H-shaped tapered member with different boundary constraints under different loads. The simplified formulas was got by the software of Mathematica. Compared with the results of finite element analysis based on SAP 2000/API in Excel/VBA,the simplified formulas proposed in this paper are simple,accurate and easy to use.更多还原
