请问各位大侠STAAD.pro中温度荷载怎么输入,图中参数分别是什么意思
望各位大侠解答
万分感谢

    你为何不看帮助呢?
    f1,f2,f4对应你的第1图片;f3、f5对应第二图

    This command may be used to specify TEMPERATURE loads or strain loads on members, plates, and solids; or strain loads on members.


    f1 = The change in temperature which will cause axial elongation in the members or uniform volume expansion in plates and solids. The temperature unit is the same as the unit chosen for the coefficient of thermal expansion ALPHA under the CONSTANT command. (Members/Plates/Solids)



    f2 = The temperature differential from the top to the bottom of the member or plate (Ttop surface-Tbottom surface). If f2 is omitted, no bending will be considered. (Local Y axis) (Members/Plates). Section depth must be entered for prismatic.



    f4 = The temperature differential from side to side of the member. (Local Z axis) (Members). Section or flange width must be entered for prismatic.

    f3 = Initial axial elongation (+)/ shrinkage (-) in member due to misfit, etc. in length unit (Members only).

    f5 = Initial axial elongation (+)/ shrinkage (-) per unit length, of members only.







    Note

    It is not necessary or possible to specify the units for temperature or for ALPHA. The user must ensure that the value provided for ALPHA is consistent in terms of units with the value provided for the temperature load. (see Section 5.26).

    If ALPHA was provided by a material name (STEEL, CONCRETE, ALUMINUM) then the temperature here must be in degree Fahrenheit units (if English length units were in effect when Alpha was defined) or degree Celsius units (if metric length units were in effect when Alpha was defined).
