新荷载规范(TJ9—74)附录二的工业楼面活荷载的等效换算方法,曾试用于新规范修订中;也推荐给设计单位,对个别情况自行作等效换算时参考之用。兹对与附录二换算法有关的问题说明如下: (一)梁和板的换算控制简支梁按弯矩和剪力换算得到的等效荷载,一般相差较大,因此有时需要分别确定其数值。简支板一般按弯矩进行换算即可,但当集中荷载靠近支座而又用公式(附3)时,将使所得的等效均布荷载偏低。
The equivalent conversion method for industrial floor live loads in Appendix II of the New Load Code (TJ9-74) has been tried out in the revision of the new standard; it is also recommended to the design agency to refer to the equivalent conversion for individual cases. The problems associated with the appendix II algorithm are described as follows: (a) The conversion of beams and slabs is equivalent to the equivalent loads obtained from the conversion of bending moments and shear forces. Generally, there is a large difference between them. Therefore, it is sometimes necessary to determine the values. . The simple support plate is generally converted by bending moment, but when the concentrated load is close to the support and the formula (Appendix 3) is used, the resulting equivalent uniform load will be low.
