Shape Optimization of Assembled Single-Layer Grid Structure with Semi-Rigid Joints [PDF]

Procedia Manufacturing, 2020
This paper takes the effect of the semi-rigid joints into account to optimise the assembled free-form single-layer grid structure. Based on the experimental results of the semi-rigid joints, finite element models of single-layer grid structure with semi ...

Subassemblage with semi-rigid joint

Computers & Structures, 1995
The finite element technique is employed to analyse and perform a parametric study on cold-formed thin-walled column subassemblage with a semi-rigid joint. Besides large displacement, the analysis also considers the area of contact between the fastener, connector and the member in the vicinity of the joint. Results obtained from a series of preliminary

Experimental study on semi-rigid composite joints with steel beams and precast hollowcore slabs

Journal of Constructional Steel Research, 2006
NoThe concept of semi-rigid composite connection has been widely researched in the past; however, most of the researches are limited to composite joints with metal deck flooring and solid concrete slabs.

A Study of Semi-Rigid and Nonlinear Behaviour Of Nailed Joints in Timber Portal Frames

Journal of Forest Engineering, 1996
In this paper a study is made of the semi-rigid and non-linear behaviour of nailed knee joints in timber frames. A numerical analysis is applied to the non-linear deformation of the joints.

Analysis of frames with semi-rigid joints

Computers & Structures, 1994
Summary: We present a method to determine the load capacity as well as end member forces and deformations of frames with partial rigid joint connections by using the direct stiffness method. The connections are modeled as rotational springs, attached at the ends of framed members.

Reliability Analysis of Steel Frames with Semi-Rigid Joints

Civil-Comp Proceedings, 2009
The aim of this study is to investigate the reliability analysis of the steel frames with semi-rigid beam to column joints under earthquake loads by developing an algorithm composed of common reliability analysis techniques. The rigidity and the strength of the semi-rigid joints are determined according to the component method.

Advanced Method for Semi-Rigid Joints Design

Applied Mechanics and Materials, 2015
In this paper was presented analysis of the background and was found the most appropriate ways to consider joints stiffness. The design process algorithm is proposed in order to take into account nonlinear stiffness characteristic, complex of economic, ecologic and safety factors for the different joint types.

Tubular Steel Truss Design Using Semi-Rigid Joints

Computing in Civil and Building Engineering (2014), 2014
Despite the fact that semi-rigid nature of steel structures joints is well-known for several decades the truss design is constantly being carried out with ideally hinged joints in the finite element models. In some recent studies the stiffness of welded tubular truss joints have been defined as well as the member buckling lengths in the trusses.

Channel frames with semi-rigid joints

Computers & Structures, 2001
Abstract The analysis and tests of cold-formed thin-walled channel frames including nonlinear flexible or semi-rigid connection behaviour is presented. The semi-rigid connection behaviour is modelled using a mathematical approximation of the connection flexibility or moment–rotation relationship.

Influence of semi-rigidity of joints on the behaviour of timber structures

Progress in Structural Engineering and Materials, 2000
The review starts by identifying the conditions for taking account of the semi-rigid behaviour of joints with dowel-type fasteners, i.e. well-defined load–displacement behaviour, no initial slip and reliable ductility. It is described how reinforcing a wood member perpendicular to the grain with fibre fabrics, plywood or densified veneer wood ensures ...
