Title
Earthquake and Wind Forces in the Structural Reliability
Abstract
In the common sense, the earthquake and wind forces are the accidental loads for the structures, and the minimum load requirements adopt 1.0 as the load factors in the structural design codes recently. In the earthquake force, the Newtonian mechanics, F=ma, can simulate the computational data accurately, and the load factor of the earthquake force can adopt 1.0 as the minimum load requirements. However, the wind force is not easy calculated accurately by hands, and the actual wind force may be computed by the ANSYS CFX or ANSYS Fluent. Compared with the CFD software, the load factor of the wind force shouldn't be 1.0 for the different structural shapes, conditions, or surfaces of facing the wind, and the minimum load requirements should provided the suitable load factors of the wind force to simulate the computational data of the CFD software. Both of the earthquake and wind forces are the accidental loads, but the wind force is harder to calculate accurately by hands.
