Structures from first principles!
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
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
Column base plates are provided beneath steel columns in order to transmit the applied design forces safely to the foundations. Steel columns are heavily loaded and their cross-sections are typically small…….
Concealed concrete beams are beams whose depth are kept equal to the thickness of the supported slab. They are normally reinforced separately from the slab, having longitudinal bars and stirrups like a drop beam.
he choice of the slab type and form is very critical for the other structural elements and overall stability of a structure.
Steel columns in simple construction are the most popular type of columns encountered in multi-storey steel buildings in practice
Torsion in structures is something that is best avoided as far as possible. This is because the twisting of structural elements generates large internal forces which result in a significant increase in element sizes and possibly even change in form
At approximately 7pm that day, guests heard popping noises moments before the fourth-floor walkway fell into the second-floor walkway. Both walkway then fell to the ground killing 114 and severely injuring over 200 persons
Fatigue is a type of failure that occurs when a material fails at loads below the specified yield strength. It usually occurs from stress from cyclical loading over a period of time
. In this post, we are going to consider how to design concrete shear walls according to Eurocode 2.
