Elasto-plastic large deformation analysis of thin-walled structures

A computer method for nonlinear inelastic analysis of 3D semi-rigid steel frameworks

“…The proposed relations modify the force-strain relations proposed by the Albermani [16] in order to simulate a nonlinear variation of the cross-section axial and flexural rigidity. The behaviour of a cross-section subjected to the combined action of axial force and bending moments is expressed in a set of equations relating the bending moments (axial forces) and the flexural (axial) rigidity for a certain value of axial force:…”

Modeling of retrofitted steel transmission towers

“…Albermani and Kitipornchai [7][8][9][10][11] proposed an analysis program for transmission towers. In their program, structural elements were defined by a stiffness matrix; the material nonlinearity was addressed by resultant yielding surfaces and a lumped plasticity approach; and the geometric nonlinearity was considered by detecting the accumulated stress on the elements' stiffness and detecting continuing changes in geometry.…”

Direct analysis for high-strength steel frames with explicit-model of residual stresses

“…Many researchers such as Meek and Tan [7], Chan and Kitipornchai [8], Chan [9], Bridge et al [10], Chan and Zhou [11], Chen and Chan [12], Izzuddin [13], Spacone et al [14], Liew et al [15], Neuenhofer and Filippou [16], Pi et al [17,18], Surovek-Maleck and White [19], Surovek-Maleck et al [20], Al-Bermani and Kitipornchai [21], Li et al [22], Liu and Li [23], Wang and Liu [24] and Zubydan [25] proposed various numerical techniques for nonlinear analysis of frames.
