It is well known that the current design rules adopted by international codes such as ISO 14346 and guides, e.g., CIDECT guide No. 3, for chord sidewall failure in mild steel rectangular hollow section (RHS) joints under brace axial compression are considerably conservative, if RHS adequately supported out-of-plane. This paper presents an investigation into using grades up to S960. Representati...

Problem statement: Rectangular steel plates are widely used in various steel structures and steel industries. For a proper design of steel plate structures and efficient use of material, the behavior, strength, buckling and post-buckling characteristics of plates should be accurately determined. Approach: Considering the significance of this matter, lateral vibration of thick rectangular plates...

The stability of axially loaded steel columns with compact rectangular hollow sections at elevated temperatures is studied in this paper. current Eurocode model for checking the buckling resistance fire was developed on a similar basis to that ambient conditions. Due effect complex non-linear behaviour fire, standard design not always fully appropriate, and certain parameter ranges may give uns...

Abstract: A finite element model is verified accurate enough to simulate the static test of one reinforced-concrete frame with specially shaped columns subjected to the loss of a ground corner column. As the frame sustained loads primarily depending on the beam resisting mechanism in the test, four related parameters, namely the height of beam section, rebar ratio of beam, rebar ratio of slab a...

The structural behaviour and design of cold-formed steel square rectangular hollow section (SHS RHS) beam–columns, made both normal high strength steels, are investigated in the present study through a comprehensive numerical modelling programme. Refined finite element (FE) models were first established calibrated against collection existing member test results from literature. Following this, ...

From the past earthquake events, m at the exit while they are trying to go out of the bu the exit doors are unable to be opened. The door is it deviates from its the original position. The aim o develop and evaluate a new type safety door that ke in its original position or keeps its edge angles pe and post-earthquake. The proposed door is c components: outer frame joined to the wall, inner and...
