Calculation of Transfer Coefficient of Rigid Beam with Two Ends under Three Different Load Arrangements

根据构件最大允许转角限值,验证了挠度曲线近似微分方程求解形状函数在抗爆设计中的适用性;采用《Introduction to Structural Dynamics》中荷载和质量传递系数的计算原理,对两端刚接梁在两个集中载荷对称布置、三个集中载荷均匀布置以及对称三角形载荷布置三种不同工况的传递系数进行推导分析,并对GB 50779—2012《石油化工控制室抗爆设计规范》附录B中的部分数据进行纠正和补充。

According to the maximum allowable rotation angle limit of the component,the applicability of shape function solved by approximate differential equation of deflection curve in anti-explosion design was verified.Based on the calculation principle of load and mass transfer coefficient in"Introduction to Structural Dynamics",the transfer coefficient of rigid beam with two ends under three different working conditions,namely symmetrical arrangement of two concentrated loads,uniform arrangement of three concentrated loads and symmetrical triangular load arrangement,was deduced and analyzed,and some data in Appendix B of the"Code for Design of Blast Resistant Control Building in Petrochemical Industry"(GB 50779—2012)were corrected and supplemented.
