Three-dimensional transient deformations of clamped flat and doubly curved polycarbonate (PC) panels impacted by a rigid smooth hemispherical-nosed circular cylinder have been numerically studied by the finite-element (FE) method to delineate effects of the panel radius of curvature to its thickness ratio on their penetration resistance. The PC is modeled as thermoelastoviscoplastic with the ef...

The connection with opening on beam web is analyzed by Finite Element Program ABAQOUS. The optimal opening sizes and location are determined under the static loads. The factors to influence the formation of plastic hinge in beams and columns withstand static load are considered. Conclusions are drawn that the formation position is not only related with the web height h, but also with flange wid...

Improper seismic design of buildings can lead to collapse and severe damage due natural unpredictable earthquake loads. Based on a comprehensive analysis the effect quantity reinforcement frame plastic hinge formation building at wall buildings, this paper proposes rational method for by means control protect lives property people ensure stability building.

Abstract--Simplified procedures for finite-deformation analyses of space frames, using one beam clement to model each member of the frame, are presented. Each element can undergo three-dimensional. arbitrarily large, rigid motions as well as moderately large non-rigid rotations. Bach element can withstand three moments and three forces. The nonlinear bending-stretching coupling in each element ...
