Structural steel frames exhibit significantly geometric and material nonlinearities which can
be captured using the second-order inelastic analysis, also known as advanced analysis …

Steel frames are used in many commercial high-rise buildings, as well as industrial
structures, such as ore mines and oilrigs. Enabling construction of ever lighter and safer …

This paper presents an efficient inelastic and large deflection analysis of space frames using
spread of plasticity method. New accurate formulae are proposed to describe the plastic …

Frame elements may be subjected to significant bending moments about cross-sectional
minor axis such as space frame elements and struts that buckle about minor axes. In some …

A generalized numerical model for predicting the structural integrity of self-anchored cable-
stayed suspension bridges considering both geometric and material nonlinearities is …

Beam structures undergoing finite deflections and rotations in space have extensive
application in the subsea industry particularly for the analysis of holistic systems with larger …

A simplified model for predicting second order inelastic behavior of steel frames is
developed. New empirical formulae are developed to describe the tangent stiffness of steel …

This paper presents a method for nonlinear dynamic analysis of frames subjected to
distributed loads, which is based on the semi‐rigid technique and moving node strategy …

This paper describes a new force-based hinge element implemented in the framework of the
Large Increment Method (LIM). The element can be of arbitrary cross section and is capable …

In this paper a boundary element method is developed for the nonlinear analysis of beams
of arbitrary doubly symmetrical simply or multiply connected constant cross-section, taking …
