Steel sections must be classified before a design can be carried out. This is because steel sections are highly subjected to large compressive stresses and could possibly fail through buckling if the plates comprising the steel section are very slender
Five years into the night of 18 January 1978, when the Civic Center had been exposed to its heaviest snow load since construction – heavy, but still only half of the design load. At 4:19 that morning, with the arena empty, the 1270t space frame collapsed in its entirety (see post cover mage). What was most disturbing, though, was that just six hours ago, more than 5,000 people were sitting below, watching a basketball game.
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
The principle of virtual work sometimes known as the “unit-load” method was developed by John Bernoulli in 1717. It is a direct application of the principle of conservation of energy
. In this post, we are going to consider how to design concrete shear walls according to Eurocode 2.
Thus, one of the methods of ensuring lateral stability and avoiding excessive lateral deflection is by deploying shear walls across the width of the building to resist the lateral forces.
Flat slabs are reinforced concrete slabs supported directly on columns, without beams. They are sometimes thickened at the columns to form column drops.
Picture the scenario, you’ve been tasked with the design of a complex large stadium roof and interestingly you’ve just received your new state of the art structural analysis software package. It’s exciting and going to be a perfect chance to demonstrate what can be accomplished if you have the right technology.
Waffle slabs are not different from a ribbed slab, their design is indeed based on the same principle as the ribbed and troughed slab system.…
