Rolled Steel Sections

  Rolled Steel Sections       Structural steel sections are hot rolled into different shapes and sizes to form the different sections. Cross section and size are governed by functional requirements, dimensional and weight capacity of rolling mills, arrangement of material for optimum structural efficiency. In a rolling mill molten steel from furnace is poured into continuous casting system where steel solidifies but it is not allowed to cool completely. Then hot steel passes through series of rollers. Such series of rollers squeezes steel into desired cross sectional shape. If the load to be resisted is small single rolled steel sections are used. If the single section is insufficient, single sections are combined or built up with angles/ channels/ I sections with or without cover plates and /or laced, providing sufficient resistance to heavy loads. Most commonly used hot rolled steel shapes are as follows: 1. Rolled Steel I -Sections 2. Rolled Steel C...

How to Use Optical Square and Open Cross Staff

Offsets can be accurately set up, particularly long offsets, by use of optical instruments like cross staff or optical square etc.    a) Cross Staff:             Two pairs of vertical slits, mounted orthogonally on a pole staff constitutes a simple instrument for setting out normal offsets as depicted in Figure. Each pair of slits can form a line of sight. It is fixed on a stand. Two persons are required to operate cross staff. Use of cross staff: 1. To find a foot of perpendicular on chain line 2. To set out the perpendicular from a given point.   b) Optical Square: It may be noted that at least two surveyor’s are required to set normal offsets while using cross staff. This disadvantage can be overcome if optical square is used for this purpose as only single surveyor can perform this task. Principle of optical square:   The angle between the first incident ray and the final reflected ray is twice that of t...

Methods of Structural Design

Methods of Structural Design   There are many methods of design out of them following two are more popular: 1. Working Stress Method. 2. Limit State Method.   1. Working Stress Method: In this method, uncertainties such as correct estimation of load, possibility of occurrence of higher design load, material imperfection and geometrical imperfections in the structural members were taken into account in one single factor known as factor of safety. A particular section just reaching to yield stress at a maximum stressed fiber is considered to be a benchmark for estimating the capacity of the steel. Structural members are not allowed to stress more than allowable stress to ensure perfect elasticity. Different factors of safety were used to arrive allowable stresses for different types of stresses in structural members such as beam, column, tension member, base plate and fastners. Using estimated working/ service loads and their logical combinations the sections are desig...
