According to the continuum mechanics principle, the updated Lagrangian formulation was employed to develop three dimensional beam element geometrically nonlinear analyses, which includes joints large displacements and large rotations. By using nonlinear step by step integration procedure the structure dynamic stability under horizontal input, vertical input and dual direction input were analyzed. The peak value of input earthquake wave is an important parameter, which reflects the earthquake input energy. Based on structure dynamic stability critical load simplified calculating method, an earthquake acceleration peak value is assessed under which structural dynamic stability can be guaranteed. The affections of initial geometry imperfection and initial static load for structure dynamic stability under strong earthquake are analyzed.

The dynamic performance test of dam concrete is a key problem to the construction of high arch dam at present. As viewed from a few dynamic tests of dam concrete at home and abroad, the wet screened concrete was used in all tests under the conditions of no initial load, so that the measured indexes from those tests could not truly reflect the actual performance of the dam concrete. Therefore, the test and study on the dynamic compressive, bending and tensile parameters of fully graded concrete...

The dynamic performance test of dam concrete is a key problem to the construction of high arch dam at present. As viewed from a few dynamic tests of dam concrete at home and abroad, the wet screened concrete was used in all tests under the conditions of no initial load, so that the measured indexes from those tests could not truly reflect the actual performance of the dam concrete. Therefore, the test and study on the dynamic compressive, bending and tensile parameters of fully graded concrete under the load conditions of high arch dam or under the conditions of different initial static loads has important application prospect and is suitable to promote the development of this discipline.
