Shear Capacity of Concrete Beams without Shear Reinforcement under Sustained Loads: Literature Survey

Concrete is a multiphase granular material consisting of aggregate particles of various sizes and irregular shape, embedded in hardened cement paste. The physicochemical processes during the hardening of the cement cause air voids, micro cracks and interfacial bond micro cracks. As a consequence of this heterogeneous structure, concrete displays...

Shear Capacity of Concrete Beams without Shear Reinforcement under Sustained Loads: Experimental Tests

Concrete is one of the oldest and most widely used construction materials in the world and possesses many unique qualities such as versatility, aesthetic appeal, eco-friendliness, cost-effectiveness and availability. Increasingly, architects and engineers are making concrete their material of choice. Its strength, durability and natural thermal...

Experimental Investigation on Time-Dependent Flexural Crack Growth: Experimental tests and Analytical Model

The experimental investigation concerns to the behaviour of plain concrete beams with a single notch under sustained loading. The notch is located at the bottom in the middle of the beam. In order to get insight into the short-term capacity of the beams, nine specimens were tested in short-term loading. The experimental program comprised four...

Shear Capacity of Concrete Beams under Sustained Loading

Long-term tests on large-scale concrete beams without shear reinforcement, which are tested for more than two years under sustained loading close to the ultimate shear capacity (load ratio ranging from 87% to 95%) under climate controlled condition, show that sustained loading has no significant effect on the shear capacity. Although many...

The feasibility of removable prefab diaphragm walls

A diaphragm wall is a cast in-situ reinforced concrete retaining wall applied in, among others, quay walls. The main advantages of this type of retaining wall are that it can be made in almost every preferred length and that it can resist high structural loads. However, there are several disadvantages: sufficient concrete cover on the...

Zettingsgedrag en capaciteit van mootvoegen in zinktunnels

Het rijkswegennet in Nederland telt 57 tunnels, belangrijke en veelal onmisbare schakels. Deze kostbare objecten vragen in beheer en exploitatie de nodige aandacht met name als ze de ontwerplevensduur naderen. Circa een derde, voornamelijk afgezonken tunnels, is halverwege deze levensduur

Lowering the Beneluxtunnel

As a result of the persistent increase of container vessel dimensions, future problems regarding navigation draught in the presence of tunnels are becoming more likely to occur. Hence, possible solutions to this problem have been investigated for the Beneluxtunnel. Several design options have been elaborated to determine the technical and...
