Abstract: A new concept of instantaneous secant stiffness is proposed and used for nonlinear elastic‐plastic analysis of steel space structures, which replaces the Newton‐Raphson technique (the instantaneous tangent stiffness method). ...

Abstract: A second‐order nonlinear analysis of steel space structures has been presented. Of the two types of nonlinearities, material and geometric, only geometric nonlinearity has been considered. The material of the structure ...

Abstract: Prediction of flutter critical wind velocity is of major concern in the wind resistant design of long-span cable-supported bridges. A full set of 18 experimental flutter derivatives in the past has not been used in the ...

Abstract: Alongwind and acrosswind response of self‐supporting reinforced concrete and latticed steel towers is studied analytically as well as experimentally. The analytical approach utilizes existing methods of analysis with certain ...

Abstract: A formulation for analytical study of cable roof systems is presented wherein the flexibility of supports bounding the roofs is accounted for. The analytical work is based on the finite element method and accounts for ...
