Drip Inducer in Structures | Water Cut & Water Shedding Requirements

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 »

Shear Wall | Functions & Loads Transfer Mechanism | Design Example of Shear Wall

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 of Concrete & Concrete Cubes | What | How

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 »

3 Major Design Philosophies: Working Stress, Ultimate Load and Limit State

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 »

How is Working Stress Method (ASD) different from Limit state method (LRFD or LFD)? Assumptions, Advantages and comparisons

How is Working Stress Method (ASD) different from Limit state method (LRFD or LFD)? Assumptions, Advantages and Comparisons Limit state method (LRFD or LFD) “A limit state is a condition beyond which a structural system or a structural component ceases to fulfill the function for which it is designed” Various limit states are Strength limit… Read More »
