Different Loads on a Structure

Before designing any structure or the different elements such as beams and columns, one has to first determine the various natural and man-made loads acting on them.These loads on a structure may be due to the following: Mass and gravitational effect, examples are dead loads, imposed loads, snow, ice and earth loads and hydraulic pressure.… Continue reading Different Loads on a Structure

Basic Structural Elements

An RC structure consists of different structural elements. It may also contain non-structural elements such as partitions and false ceilings. The function of any structure is to resist the applied loads effectively and to transmit the resulting forces to the supporting ground without differential settlement. At the same time the structure should also satisfy the… Continue reading Basic Structural Elements

Reinforced Concrete Structural Forms

Structural design is an art of selection of the most suitable system for a given structure. The arrangement of beams and columns to support the vertical (gravity) loads and the selection of a suitable structural system to resist the horizontal (lateral) loads pose a great challenge to the structural engineer, as these factors will determine… Continue reading Reinforced Concrete Structural Forms

Case Study: Mantri Square Mall Cantilever projection collapse Report

Preamble: The commercial building Mantri mall, is a conventional RC framed structure with two basements, ground and three upper floors. The building was built during 2006 to 2008. It was reported that part of this commercial building located at Malleshwaram, Bengaluru was collapsed at about 1.30PM on Monday, 16th Jan 2017. The scope of this… Continue reading Case Study: Mantri Square Mall Cantilever projection collapse Report

Mix Proportioning of Concrete

The following data is required for concrete mix proportioning of a particular grade of concrete: Exposure conditions of the structure under consideration (see table 3 of IS 456:2000). Grade designation – The minimum grade of concrete to be designed for the type of exposure condition under consideration (see table 3 and table 5 of IS… Continue reading Mix Proportioning of Concrete

Non-destructive Testing

Non-destructive tests are used to find the strength of existing concrete elements. Half-cell electrical potential method to detect the corrosion potential of reinforcing bars in concrete. Schmidt/Rebound hammer test to evaluate the surface hardness of concrete. Carbonation depth measurement test to determine whether moisture has reached the depth of the reinforcing bars, thereby leading to… Continue reading Non-destructive Testing
