Six Step Guide to Designing a Rolled Steel Beam Here are a few simple steps that are to be followed for the design of Rolled Steel Beam: Step one Calculate the maximum Bending Moment and Shear Force Step two Depending upon whether the beam is laterally restrained or unrestrained, calculate the permissible stress in bending … Read more Guide to designing a Rolled Steel Beam

## Methods of Structural Design | Design of Steel Structures

Structural design is the science of studying the Mechanics of a structure. Designing the skeleton of a building determines the real strength of the structure.

If the structure is externally beautiful and internally weak, it results into dramatic structural failure.

In this article, we are going to discuss in detail about the “Various Methods of Structural Design”.

All parts of a structural steel framework of a structure shall be capable of sustaining the most adverse combination of dead loads, the prescribed super imposed roof and floor loads, wind loads, seismic forces where applicable, and any other forces or loads to which the building maybe reasonably subjected without exceeding the permissible stresses.

The following methods may be employed for existing steel framework:

1. Simple design
2. Semi-rigid design
3. Fully rigid design
4. Plastic design

## Column Bases | Design of Steel Structures

Column bases are structural elements used in the design of steel structures to transfer the column load to the footings.

#### Types of Column bases

1. Slab base
2. Gusseted base

#### Slab Base

Slab bases are used where the columns have independent concrete pedestals. A thick steel base plate and two cleat angles connecting the flanges of the column to the base plate. In addition to these, web cleats are provided to connect the web of the column to the base plate. These web cleats guard against the possible dislocation of the column during erection. The ends of the column and also the base plate should be mechanized so that the column load is wholly transferred to the base plate.

#### Area of base plate= (load of column)/(permissible bearing stress in concrete)
