Plane Trusses and Frames

INTRODUCTION

A structure refers to a system of connected parts used to support a load. Important examples related to civil engineering include buildings, bridges and towers. In other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems and electrical supporting structures are important.

STRUCTURAL ELEMENTS

Tie Rods

Structure members subjected to a tensile force are often referred to as tie rods or bracing struts. Due to the nature of load, these members are rather slender and are often chosen from rods, bars, angles or channels.

Beams

Beams are usually straight horizontal members used to carry vertical loads. Depending upon the type of supports, beams are classified as follows: ...
