Abstract:Diaphragm assembly is investigated. Discretised into various elements, the stressed skin diaphragm assembly is analyzed using the nonlinear finite element theory. The working behaviors of the diaphragm assembly under shear loads in plane and various factors that affect its shear capacity, failure modes and mechanism are studied. The results of finite element are compared with those recommended in Europe Recommendations (EUR), and it is showed that they coincide well.

Keywords:diaphragm assembly; nonlinear finite element; shear behavior
