The most common and conventional method of designing against shear in reinforced concrete structures is via the provision of shear-links (stirrups). However, in certain scenarios, shear cannot be resisted via the use of links alone, especially where the applied shear-force is enormous. In such scenarios, a very effective way of resisting shear in concrete is by combining shear-links with the provision of bent-up bars
At approximately 22 minutes past 6:00 pm on 21st of August 2009, a train was travelling across the viaduct, when the train driver suddenly noticed a portion of the viaduct had begun to collapse
A windpost is a vertical element offering lateral support to cladding element typically made from masonry. Historically masonry elements were required to sustain only vertical forces and designed as principal load bearing elements
A significant opening within masonry walls will always require a lintel of some sort to bridge over it. In contrast to popular opinion, lintels are structural elements though classified as secondary structural elements whose primary function is to support the masonry that arches over the opening
For every structure, frame stability is an important area of consideration. Designers of structural steel-work were the first to recognize the importance of considering the stability of steel frames in BS-5950.
This is the first post in a series on concrete bridges, the series will discuss in detail the various aspects of concrete bridge design and construction. This post introduces the concept and the key benefits of using concrete for bridges
Inspection of activities on-site during construction is a high-risk operation that requires expertise and experience. Site inspections are of paramount significance as they aim to minimize the risk of accidents arising within the construction structure – even though they never guarantee non-occurrence of accidents. They can only be carried out by those familiar with the structure of the works and the constraints of the construction methods.
The designer of a composite floor has a number of basic and obvious decisions to make, including what type of beam to use and what type of decking. He or she also has some more detailed decisions, such as the choice of propped or unpropped construction, whether the steel beams will be restrained during construction, and how will the upper surfaces of the slabs be levelled during concreting
Timber as a structural element is not new, in fact, it predates the development of concrete and steel as structural members, dating back many centuries
Some failures are caused by the most stealthy human factors: corruption and greed. This situation is even worse in the third-world countries where the use of sub-standard materials, faulty construction and cutting corners around standard specifications is highly prevalent.
