A new methodology is proposed for investigating compressive failure behavior of cement paste at micrometer scale. Micropillar geometries are fabricated by focused ion beam milling on potential calcium...
Concrete isn’t thought of as a plastic, but plasticity at small scales boosts concrete’s utility as the world’s most-used material by letting it constantly adjust to stress, decades and some...
The horizontal shear strength of the interface between prestressed concrete hollow core slabs and cast-in-place concrete topping slabs was evaluated through a set of 24 push-off experiments. The push-...
In theory of concrete it is assumed that concrete composites are isotropic on a macro scale. For example, it is assumed that a floor slab’s or a beam’s strength is identical in all directions and its ...
Ultrasonic pulse velocity (UPV) and rebound hammer (RH) tests are often used for assessing the quality of concrete and estimation of its compressive strength. Several parameters influence this propert...
Concrete is the most undisputable and indispensable material being used in infrastructure development throughout the world. Umpteen varieties of concretes (FAC, HVFAC, FRC, HPC, HSC, and others) were ...
Rehabilitation of existing infrastructure has become a priority in recent years as an alternative to the daunting costs of rebuilding structures. Traditional repair methods have drawbacks, many of whi...
It is important to select materials having both high strength and good ductility in most engineering applications. This is also true for high temperature problems and the requirement of high creep str...
This paper presents part of the results of an ongoing laboratory study carried out to design a structural lightweight high strength concrete (SLWHSC) made with and without ternary mixtures of cement-f...
Twelve full-scale beam specimens (2000 × 300 × 200 mm) were tested in positive bending with the loading system designed to determine the effect of self-compacting concrete (SCC) and the diameter of re...
Buildings in Japan must be designed and constructed according to Building Standard Law, the Enforcement Order and the Notification by Ministry of Construction and the Ministry of Land, Infrastructure ...
The use of high-strength concrete in reinforced concrete slabs is becoming popular in Australia and other countries. Current design provisions of AS3600 and other major codes throughout the world are ...
This paper describes a method which can be adopted to improve the torsional and also distortional strength of thin-walled cold-formed steel columns used in pallet racking systems. Elastic buckling ana...
This paper presents the study of an analytical model to estimate the strength of a thin-walled channel steel section beam subjected to axial-compressive loads. The model is based on two different meth...
This investigation presents the use of Fiber Reinforced Polymer (FRP) composite systems in upgrading existing reinforced concrete frames to meet strength and ductility requirements laid out in recent ...
