Nowadays, the focus of reliability-based validation of the post-fire bearing capacity of structures is on multi-storey buildings used for dwellings or offices due to the high human impact related to the use of the building. Research has been done using first order reliability-based methods to assess the behaviour of simple single isostatic concrete slabs, which is commonly used in this type of buildings. But, the knowledge of the post-fire ...

There has been a significant increase in stainless steel investigations related to steel construction in the last few years, contemplating numerical and experimental studies. This fact is associated with the excellent properties these materials can provide compared to carbon steel, such as corrosion resistance, durability, fire resistance, and added aesthetic value. On the other hand, the current standards and design codes are still mostly based ...

It is recognized a distinct structural behavior attributed to stainless steel grades in which stainless steel elements are associated to nonlinear stress-strain curves without a defined yield plateau and large strain hardening zones. The purpose of the present investigation is to contribute with further experimental and numerical analyses in order to assess the structural performance of the overlap shear connections in bearing in thin-walled ...

The connections play an important role in the overall behaviour of the structures. Therefore an adequate structural design taking into account both safe and economic criterion is necessary. The structural design of stainless steel bolted connections using actual codes can provide inadequate design capacity mainly due to the use of similar rules based on analogies from mild carbon structures. Thus, the purpose of this paper is to evaluate the ...

This paper presents the improvement of interfacial strength of stainless steel-polymer hybrid materials by silane surface treatment. Two different deposition routes, a wet chemical dipping process and an atmospheric plasma deposition route were chosen to deposit the silane on the stainless steel surface. The conditions of both deposition routes were optimised. Pull-off testing (dolly testing, in accordance with ISO 4624:2002) was used to ...

The use of stainless steel in structures has been improved; nevertheless, the appli-cation of this material is not considered trivial by most designers,as there as still limited design codes providing specific rules. Current codes provide conservative approaches in certaincases, which do not corroborate with the objective of reducing the initial cost of projects incorporating stainless steel. In order to contributeto an adequate ...
