Determination of the loads for which a structure has to be proportioned is an important task in a design. The various loads that are likely to act on a structure and the possible combinations of such loads that can act are all points to be considered. Dead load refers to the weight of a structure. It is necessary to estimate [...]
In this article we will discuss about the types and design of tension members used in steel structures. Types of Tension Members: 1. Minor Types of Tension Members: A. Bars and Rods: These are commonly attached to other members by bolting or welding. These are slender and are meant to resist tension only. These minor tension members are of the [...]
In this article we will discuss about the column connections and angle struts of compression members in steel structures. A compression member is a very commonly encountered structural member whose function is to receive a compressive force. A compression member is known by various terms like column, stanchion, strut etc. Fig. 7.1 shows the various types of compression members. A [...]
The following article will guide you about how to design base plates used in steel structures. Column Base: While a foundation is necessary for a column to distribute the column load on sufficient area of the soil so that the bearing capacity of the soil is not exceeded, it is also equally important that the column load should be applied [...]
In this article we will discuss about how to make connections in steel structures. Bolted Connections: A. Eccentric Bolted Connections: The resistance offered by a weld was entirely to prevent a linear or translatory displacement of a plate or member connected. There are also circumstances in which the welds provided for a connection may have to offer not only a [...]

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. Bolted Connections in Steel Structures 2. General Principles in Bolted Connection Designs 3. Assembly 4. Design Strength 5. Tension Capacity 6. Prying Forces 7. Bolt Subjected to Shear and Tension 8. Assumptions. Bolted Connections in Steel Structures: In steel constructions, connections become necessary at various places. Connections become necessary to connect the [...]
In this article we will discuss about how to design laced and battened columns. To carry heavy loads a built-up column also called an open web column is provided. Such a column may consist of different components like, two channels, four angles, two I-sections etc. If an arrangement to connect or stitch together the individual components of such a column [...]
