摘要：

A three-dimensional nonlinear finite element model of a light-frame wood building was created and used to determine internal forces caused by wind pressure in shear walls. Comparing the results with current design procedures led to two fundamental observations: (1) The assumption of current procedures that one-half of the load is transferred directly to the foundation is correct; (2) calculating internal forces in the shear walls by simple- and continuous-beam models does not reflect the real situation and may lead to erroneous results. Linear and nonlinear models assuming the roof diaphragm as a rigid beam on elastic supports were proposed, analyzed, and compared with the finite element solution of an experimentally verified model. Satisfactory accuracy can be achieved by using the rigid-beam analogy if the shear stiffness of the walls is known.
