Shape Optimization of Hollow Concrete Blocks Using the ...
Abstract:Hollow concrete blocks are one of the widely used building elements of masonry structures in which they are normally loaded under combined action of shear and compression. Accordingly and due to their structural importance, the present study intends to numerically search for an optimum shape of such blocks.

Concrete Block Vs. Brick | Hunker
According to the Masonry Advisory Council, all concrete blocks must have a minimum compressive strength of 1900 pounds per square inch. Many dense blocks are stronger than this. According to Mechanical Properties of Unreinforced Brick Masonry, the average concrete block can withstand 3500 psi, while the average clay brick can withstand 3000 psi.
Calculating the Depth of the Compressive Stress Block ...
Mar 17, 2017· The first step is calculate the crosssectional area of the tensile steel reinforcement in the reinforced concrete masonry beam. It is equal to the number of steel bars times the crosssectional area of a single steel reinforcement bar. The second step is .
NONLINEAR BEHAVIOR OF ONE WAY REINFORCED .
Hollow block slab is one type of the voided slab which depends on reducing the selfweight by removing the ineffective zone of concrete. Hollow blocks are used to fill portions of the slab thickness; this results in deeper arm for the rebar while saving considerable amount of concrete and hence the own weight of the slab. The
