CAESAR IIWIND LOADSCARGAS DE VIENTO

Wind is occasional and dynamic but we simulate the wind in static way. To activate wind we mark the check box Wind/Wave and we enter the shape factor, 0.5 - 0.65. Normally we use 0.6

WIND LOADSThe load Case editor includes the wind loads like the sismo loads. The loads are considered as operation loads, and the its effect is isolated to be combined with the sustained loads and to verify stress

In the TAB WIND LOADS is defined the wind standard and the wind profile together with the wind direction1415
