Equations of Static Equilibrium

Equations of Static Equilibrium Equations of Static Equilibrium: Consider a case where a book is lying on a frictionless table surface. Now, if we apply a force F1 horizontally as shown in the Fig.1(a), then it starts moving in the direction of the force. However, if we apply the force perpendicular to the book as …

Structural Idealization

In order to perform the process of structural design, one has to go through the structural analysis. The analysis includes a main step which is “Structural Idealization” To calculate the forces in the various parts of a structure with reasonable simplicity and accuracy, it is necessary to represent the structure in a simple manner that …

Structural Elements and Systems

Structural Elements and Systems: All structural systems are composed of elements. The following are considered to be the primary elements in a structure:  1- Ties: those members that are subjected to axial tension forces only. Load is applied to ties only at the ends. Ties cannot resist flexural forces. 2- Struts: those members that are subjected …

Basic Principles of Structural Analysis

Basic Principles of Structural Analysis: Structural engineering involves an extensive variety of structural systems to deal with such as buildings, bridges, sports stadiums, radio and television towers, arches, storage tanks, aircraft and space structures, concrete pavements, etc. These structures can vary in size from a single member as is the case of a light pole to buildings or …
