A multi-storybuilding from the perspective of a structural engineer is described as asolitary structure by the ethic of its height, is afflicted in such a manner bythe forces of wind or earthquake, to a degree that they impersonate itsskeletal design. Most customary block facade construction comprises of a load-bearingwalls of either wooden or steel studs, or solid stone work units with brickunits as finished walls. One can say that the bricks are functioning as alittle more than 4″ of paint.
In a basic brick framework, the brickfills in as both a structural system and exterior finishing face. Utilizingbricks in both the building’s exterior and internal structure takes advantagenot only of its masonry strength, but also, in the building’s engaging appearanceand other inborn esteems. Bricks, are primitive elements in the construction ofthe edifice, which encompass clay-bearing soil, sand, lime or concretematerials, although they can differ in innumerable classes, sizes, compositionsand properties. However, the three most prominent properties that a brickshould suffice are – strength, absorption and weather resistance. If thesefactors are satisfied, bricks make quite a durable material for masonryconstruction. Thebricks employed in this project is of cellular light weight concrete blocks(CLC blocks). Cellular lightweight concrete blocks are then catalogued in 3grades such as Grade A, Grade B, Grade C.
The comparison between the cellularlight weight concrete blocks and the conventional red bricks is based on the analysisof a residential building. The density of cellular light weight concrete blocksare comparatively lower than the conventional burnt clay bricks and even theyare absorptive, nontoxic, reusable, regenerative and can be recycled. Hence inhigh rise residential buildings, cellular lightweight concrete blocks are used asa reinstatement to the conventional burnt clay bricks. Considering howlightweight these blocks are, there is a decrease on dead load which acts onthe structure, making it lighter to a large extent. The structure beingtenuous, there will be a cutback in the reinforcement, reduction in the size ofthe member, decrement in the concrete and also by using these blocks the use ofcoarse sand for plastering purpose becomes counterproductive.
All these factorscombined together will produce a competent and cost-effective structure.
