Snow Load tab
Used to generate snow loading on a structure in accordance with the provisions of the ASCE-7-02 code.
The feature is currently implemented for structures with flat or sloping roofs. Snow load generation for members of open lattice structures like electrical transmission towers is currently not part of this facility. Hence, the feature is based on panel areas, not the exposed width of individual members.
|Floor Group||Select the floor group on which the snow load is to be applied.|
|Condition||Specify whether the load is "Balanced" or "Unbalanced." These terms are described in section 7.6, and figures 7.3 and 7.5 of ASCE 7-02.|
|Define Snow Type||Select the snow load type number. This is the number specified against the Type No. field while creating the snow load definition in Part I described earlier in this section.|
Specify the roof type from the available choices:
|Roof Obstruction||Specify whether the roof is "obstructed" or "unobstructed." This also is a term described in section Table 7-2 of ASCE 7-02.|
|Roof Slope Factor||For sloped roofs, the roof slope factor is described in section 7.4 of the SEI/ASCE-7-02. A value of 0 indicates that the roof is horizontal.|
