Strengthening of RCC beams The need for strengthening a reinforced concrete beam or a number of beams in a structure is usually caused by problems due to degradation of characteristics of materials with time, reduction in cross section, corrosion, wrong initial design or the increase in the load demand on the building when its utilized for … Read more
Punching Shear Failure In previous article we have discussed about the punching shear in flat slabs. If you have not read that you can check it at What is Punching Shear? Punching Shear in Flat Slabs. In this article we are going to discuss about the design of members for the punching shear. What is … Read more
What is a Drip Inducer or Water Cut A drip inducer also known as water cut can be a recess, protrusion, groove or a projection on an underside surface. The function of drip inducer is to interrupt and break the flow of water along the surface thereby causing it to drip off. One of the … Read more
Definition of Shear Wall Shear walls are the vertical structural element which resist the horizontal forces acting on a building structure. Shear wall can also be defined as a wall which are reinforced & made of braced panels to carry lateral forces. The thickness of the shear wall for regular buildings can be generally in … Read more
Compressive Strength The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions. Concrete mix can be designed or proportioned to obtain the required engineering and durability properties … Read more
Three Major Design Philosophies A design philosophy is a set of assumptions and procedures which are used to meet the conditions of serviceability, safety, economy and functionality of the structure. Several design philosophies have been introduced from different parts of the world. Some of the design philosophies that has been used by engineers are Working … Read more
