A FORCE-BASED FORMULATION FOR THE ANALYSIS OF 3-DIMENSIONAL INELASTIC STRUCTURAL FRAMES
TLDR
A force-based formulation for the step-by-step nonlinear (elastic-plastic) analysis of three-dimensional (3D) structural frames is presented. Expand
A force-based formulation for the 2nd order elastoplastic analysis of frames
A force-based formulation for a nonlinear optimization program that performs 2nd order analysis of plane frames is derived, under assumptions for elastic-perfectly plastic material and non-holonomicExpand

An efficient mathematical programming method for the elastoplastic analysis of frames
Abstract The elastoplastic nonholonomic analysis of frames is a nonlinear procedure in which the magnitude of the structural loading is incrementally modified using a proportional load factor, inExpand

A force-based mathematical programming method for the incremental analysis of 3D frames with non-holonomic hardening plastic hinges
TLDR
An automated, step-by-step, 1st order matrix force method is developed for the analysis of planar (2D) and spatial (3D) structural frames made of elastic-hardening plastic material. Expand
Limit Analysis of Cable-Tied Structures
Cables are frequently used to strengthen existing framed structures. They are also the main members that support bridge-decks in cable-stayed bridges. This type of structures may be idealised toExpand

A quick estimate of the strength of uniaxially tied framed structures
Abstract A quick direct limit analysis method to estimate the strength of structures consisting of beam and cable-type members is proposed. The method is based on the kinematic theorem of plasticityExpand

NUMERICAL IMPLEMENTATION OF THE FORCE METHOD IN THE ELASTOPLASTIC ANALYSIS OF FRAMES
The response of a linearly-elastic perfectly-plastic frame subjected to proportional loading, may be obtained with the use of incremental loading steps. If we take an increment of the applied loadingExpand
Numerical Analysis of Nonholonomic Elastoplastic Frames by Mathematical Programming
The strength as well as the ductility of a structure may be estimated by performing an elastoplastic analysis. In such an analysis structural loading is incre- mentally applied through a proportionalExpand
