Preface to the theme issue 'Durability and ageing of composite materials'
No full textThe issue focuses on ageing and durability of composite materials for industrial applications. Ageing and durability are two fundamental topics within the context of design and optimization of materials and structures: ageing may induce degradation and leads to premature failure. Therefore, understanding the main ageing mechanisms is of paramount importance for predicting material durability. These topics are still barely studied systematically and the main related issues are debated within mechanical, chemical, and solid-state physics research communities. This issue aims to update the current research state of the art, clarifying the interplay between chemical and physical mechanisms involved in degradation processes, and providing test protocols and design rules that account for ageing and durability. This article is part of the theme issue 'Ageing and durability of composite materials'
INFLUENCE OF BOND-SLIP ON NUMERICAL FRAGILITY CURVES AND STRUCTURAL RELIABILITY OF RC STRUCTURAL INTERNAL BEAM-COLUMN SUB-ASSEMBLY
No full textIn this paper results obtained from monotonic nonlinear static analyses performed on Re- inforced Concrete (RC) internal beam-column sub-assembly are shown. Bond-slip phenome- non between steel longitudinal bars and surrounding concrete is also taken into account in order to predict the numerical response under lateral actions of the RC internal beam-column sub-assembly investigated.
The study is addressed, through parametric models and Monte Carlo simulations, to pro- pose preliminary fragility curves for different damage states of the RC internal beam-column sub-assembly, including materials inherent uncertainties
NUMERICAL ANALYSIS ON A REVERSIBLE CONNECTION FOR STEEL MODULAR BUILDINGS
No full textModular buildings are a new type of structural system composed by prefabricated modular
units and assembled on site through inter-modular connections. These structures can form
complete building blocks with suspended ceilings and installations, including electrical and
water systems. These modular solutions can be adapted to any use like hospitals, housing
schools, etc.
This work focuses on the analysis of structural behavior on a reversible steel connection
modelling with finite element approach.
To this scope, in the paper an ideal case study is considered, characterized by steel elements.
The modules are assembled by inter-module connections that allow for rapid assembly on-
site, without any need of skilled workmanship reducing the welding and the use of bolts.
Therefore, Midas Fea NX is used to define the contact between steel elements in detail
