Abstract
This thesis presents a displacement finite element model to study the
nonlinear elasto-plastic behaviour of framed structures with latticed girder. The
nonlinear inelastic response of the theoretical behavior of framed structures with
latticed girder is predicted throughout the entire range of loading up to the point of
the maximum carrying capacity. This study takes into consideration the instability
effects caused by the axial force, geometric nonlinearity of columns, and the
material nonlinearity. In this thesis presents.all the previous published work in the
field. Also the scope and objectives of the present study are outlined in detail. The
load and boundary conditions are adopted to obtain the ultimate strength of
trussed frames (in plane failure). Various trussed beams to columns bending
stiffness ratios, as well as various ratios of trussed beam to column height, have
been studied. Furthermore, the effect of initial geometric imperfections with
various mode shapes on the ultimate loads of these frames is also studied. The
analysis was performed on single-bay trussed frames; two bays trussed frames and
trussed frames with stepped columns. The analysis was carried out using the
Ansys program. Several published cases were chosen in order to check the
accuracy of using the Ansys program results.
