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 ...
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...
The authors have proposed an equation for estimating the ultimate strength of T-shaped socket joints. However, the effect of cyclic loading and external diagphragms, applicability to the cross-shaped ...
As a method of connecting two concrete-filled circular steel tubular constructions, a simple socket joint in which a small diameter tube is inserted with the specific length to a large diameter tube ...
The ultimate flexural strength of composite steel girders with compact sections is examined through experimental investigation and elasto-plastic finite displacement analyses to develop a reduction f...
期刊信息 篇名 Behavior of steel tube and confined high strength concrete for concrete-filled RHS tubes 语种 英文 撰写或编译 撰写 作者 ZHANG Sumei,GUO Lanhui,YE Zaili and WANG Yuyin 第一作者单位 Harbin Institue of Technology 刊...
High strength concretes incorporating large amounts of silica fume (SF) are analyzed for different types of admixtures. Properties of fresh and hardened concrete were analyzed for dosages of SF betwee...
