Testing and nonlinear modelling of industrialized light-frame wooden diaphragms including optimized nailing and nonstructural sheathing

This article presents the outcomes of a large project towards the investigation of the lateral performance of full-scale industrialized light-frame wooden diaphragms. 10 full-scale diaphragms of 3.6 m by 2.4 m were tested under in-plane lateral loading (mo ...

Fire performance evaluation of GFRP-balsa sandwich bridge decks

Niloufar Vahedi

Bridges are a critical component of national infrastructures and economies. A significant percentage of bridges built all around the world are made of reinforced concrete which according to building codes have a life span between 80-100 years. However, str ...

Influence of non-structural components on the seismic response of cold-formed steel structures

Dimitrios Lignos

Shortcomings exist with respect to accounting for the influence of non-structural components, e.g. gypsum panels installed on the ceilings (floors and roof diaphragms) and walls, on the response of cold-formed steel (CFS) framed structures subjected to sei ...

Fracture mechanics-based progressive damage modelling of adhesively bonded fibre-reinforced polymer joints

Thomas Keller, Anastasios Vassilopoulos, Moslem Shahverdi, Roohollah Sarfaraz Khabbaz, Aida Cameselle Molares

A quasi-static progressive damage model for prediction of the fracture behaviour and strength of adhesively bonded fibre-reinforced polymer joints is introduced in this paper. The model is based on the development of a mixed-mode failure criterion as a fun ...

Ductility of adhesively bonded timber joints

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber engineering, adhesive bonding remains a promising, though poorly developed, joining technique that may increase the structural stiffness and capacity of timber joints and structures. Selecting ductile adhesives may further allow to c ...

Kinetic model for calcium sulfate alpha-hemihydrate produced hydrothermally from gypsum formed by flue gas desulfurization

Xuerun Li

Modeling of the kinetics of the synthesis process for calcium sulfate alpha-hemihydrate from gypsum formed by flue gas desulfurization (FGD) is important to produce high-performance products with minimal costs and production cycles under hydrothermal condi ...

Interactions between alite and C(3)A-gypsum hydrations in model cements

Karen Scrivener, Alexandra Quennoz

This paper focuses on the interactions that occur between cement phases during early hydration, especially between the hydration of alite and C(3)A-gypsum. This study shows that alite reaction is accelerated in the presence of gypsum. This acceleration was ...

Hydration of C(3)A-gypsum systems

Karen Scrivener, Alexandra Quennoz

Hydration of C(3)A-gypsum systems with different gypsum additions was investigated in terms of the phase assemblage, kinetics and microstructural development. The second stage of the reaction, which begins after the depletion of gypsum, was of particular i ...

Limestone Addition in Cement

Olga Agata Chowaniec

Addition of fine limestone provides an excellent means to reduce the amount of clinker in cement. It is now well accepted that limestone partially reacts in cementitious systems with C3A to produce hemi- and monocarboaluminate phases and as a consequence m ...

Hydration of C3A with Calcium Sulfate Alone and in the Presence of Calcium Silicate

Alexandra Quennoz

Tricalcium aluminate (C3A) is one of the main constituents of Portland cement. Even though it represents less than 10% of the total composition, its strong reaction with water can lead to a rapid setting, called flash set. Gypsum is added to regulate this ...
