Simple Stresses
Tensile Stress A body is facing tensile stress when two equal and opposite tensile forces try to stretch the body or induce tension in the body. This elongate the body. Tensile stress is denoted by ft, …
Continue readingWall Footing Design Example
Wall footing design is carried out with some assumptions that should be considered while designing. The first assumption is to consider that soil pressure is distributed linearly throughout. This can only be achieved, when resultant …

Combined Footing Problem Statement Design a rectangular combined footing to support two columns shown above. The edge column on the left has a section of 16” x 16” and carries dead & live load of …
Continue readingMoment of Inertia of a Circular Section
Moment of inertia of a circular section can be calculated by using either radius or diameter of a circular section around centroidal x-axis or y-axis. Example Find the moment of inertia of a circular section …
Continue readingMoment of Inertia of Hollow Rectangular Section
Moment of inertia is the product of first moment of area and the centroidal distance of the area from a given axis. If A.x is the first moment of area of certain section then (Ax).x is …
Continue readingCentroid of I-Section
Centroid of I-section can be found easily with respect to reference x-axis because of section symmetry around y-axis. As shown in the example below; Example Find the centroid of I-section given below. Solution Step: 1 First …
Continue readingCentriod of T-Section
Centroid of T-section can be found easily with respect to reference x-axis. This is so because T section is symmetrical about Y-axis. Centroid of T Section Example Find the centroid of T-section as shown below. …
Continue readingEngineering Section
Engineering sections are the shapes that are most commonly used in the design of civil engineering structures like I-section, T-section, L-section etc… These sections are used in building columns, roof trusses, cantilevers, bridge girders, beams, stadiums, …
Continue readingCentroid by Moment Method
Centroid by moment method is based on the principal of taking moments about any arbitrary point. Centroid by moment method states that “When a number of coplanar parallel forces acts in a certain plane, then …
