PORTAL METHOD OF APPROXIMATE ANALYSIS The portal method is an approximate analysis used for analysing building frames subjected to lateral loading such as the one shown in figure 1(a). This method is more appropriate for low rise (say height is less ...

An influence line for any given point or section of structure is a curve whose ordinates represent to scale the variation of a function such as shear force, bending moment, deflection etc at a point or section, as the unit ...

Behaviour of tension members under the action of loads for tension ties and is discussed below: Behaviour of Tension Tie: The tie is the simplest type of member in tension. When a tensile load is applied on one side of a tie ...

First moment Forces are distributed continuously over an area on which they act, it is often necessary to calculate the moment of theses forces about an axis

Continue reading## Statics of Bending: Shear and Bending Moment Diagrams

Beams are long and slender structural elements, differing from truss elements in that they are called on to support transverse as well as axial loads. Their attachment points can also be more complicated than those of truss elements: ...

Continue reading## Steel Concrete Composite Columns- Analysis and Design

A steel-concrete composite column is a compression member, comprising either a concrete encased hot-rolled steel section or a concrete filled tubular section of hot-rolled steel and is generally used as a load-bearing member in a composite framed structure. Typical cross-sections of ...

The stiffness method of analysis is the basis of all commercial structural analysis programs. The focus of this tutorial is development of these equations that only take into account bending deformations, i.e., ignore axial member deformations. Within the ...
