In this article we will discuss about the plastic bending of beams. Let us consider a beam of homogeneous material and symmetrical section subjected to a bending moment M. The distribution of bending stress follows a linear law with zero stress at the neutral axis and a maximum stress at the outermost fibres, when the deformations are within the elastic [...]
In this article we will discuss about:- 1. Introduction to Plastic Analysis 2. Plastic Moment of Resistance of a Rectangular Section 3. Moment of Resistance of a Rectangular Beam Section for a Given Depth of Penetration 4. Plastic Moment of Resistance of a Symmetrical I-Section 5. Relation between Load Factor and Factor of Safety. Introduction to Plastic Analysis: Analysis of [...]
In this article we will discuss about:- 1. Types of Beams 2. Design Considerations of a Beam 3. Classification 4. Compound Elements 5. Failure Modes 6. Lateral Buckling. Types of Beams: A beam is the most commonly encountered structural member whose function is to support loads which are resisted by its resistance to bending and shear. Beams are mostly used [...]
In this article we will discuss about:- 1. Introduction to Gantry Girders 2. Gantry Girder Sections 3. Wheel Base 4. Loads 5. Design Details. Introduction to Gantry Girders: In workshops and factories a very important and useful requirement is to have the means for lifting and moving heavy loads from one part to the other part of the shop area. [...]
In this article we will discuss about:- 1. Meaning of Plate Girders 2. Plate Girder Connections and Splices 3. Components 4. Design. Meaning of Plate Girder: A plate girder is a deep built-up beam consisting of plates (or plates and angles) meant for carrying heavy loads on large spans. For heavily loaded girders of large spans single I-sections even with [...]
Roof trusses become necessary when sloping roofs have to be provided. At places of heavy rainfall or heavy snowfall sloping roofs are necessary which have to be supported by roof trusses. Workshops warehouses, industrial buildings etc. also need sloping roofs and hence roof trusses. For many single storey buildings sloping roofs on trusses are common. When a roof is to [...]
In this article we will discuss about how to design cylindrical tanks for storing domestic and industrial water. Cylindrical tanks may have flat bottom or spherical bottom or conical bottom. A flat bottomed cylindrical tank having a height greater than the diameter is called a stand pipe. Such a tank rests on the foundation directly. The tank may also be [...]
