Strengthening of Reinforced Concrete Beam (RC Beam) | Methods

Strenthening techniques implemented on an existing building

Strengthening of RCC beams The need for strengtheningĀ 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

Axial Capacity of Steel Column or Strut

steel column in an industry

Capacity of Steel Column Columns are those structural elements which predominantly carries axial compression in a structural system. In steel construction, the column is the vertical member which is subjected to axial load and strut is the inclined member subjected to the same. Steel is a very strong material but it does lead to slender … Read more

Fillet weld for Steel Connections | Guidelines for Fillet Welds

Fillet Weld Gauge by GAL GAGE Company

Fillet weld & Strength of Fillet Weld When faces of two members are inclined at an angle, fillet weld is used. Fillet welds usually have a triangular cross-section. In order to do fillet welding, the angle between joining surfaces shall be within a range of 60 to 120 degrees. Important factors that decide the capacity … Read more

Steel Connection | Simple Connections & Moment Connections

Simple Column to Beam Shear Steel Connection with Cleat angle

Selection of Steel Connection When it comes to steel construction, steel connection is one of the most crucial design components, in terms of cost as well as integrity of the structure. If connection types and arrangements are not carefully chosen, it can account for upto 65% of total cost of the production. This is because … Read more

Drip Inducer in Structures | Water Cut & Water Shedding Requirements

Common DripInducer details and standard

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

Key Causes of Failure of Bridges | Reasons for Collapse during Construction | Bridge Failure

Failure due to Buckling of piers during construction

Failure of Bridges Total or partial failure of bridges or collapse is often wrongly attributed to poor or improper design alone. This article attempts to elaborate the root causes of collapse of road, vehicular and rail bridges irrespective of structural type. Said that flaws in construction of bridge is one of the important reasons of … Read more

Cathodic Protection | Types of Cathodic Protection | Applications

Sacrificial anode

Cathodic Protection Cathodic protection is an approach which is employed to control the corrosion that occurs on the surface of the metal by making it the cathode of an electro-chemical cell. This procedure is quite simple which involves the connection of the metal to be protected, to a more easily corroded metal which is usually … Read more

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

Shear Wall in a Building

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
