INTRODUCTION : A truss is an articulated (skeletal) structure with hinged or ball and socket joints. It is an assemblage of slender bars fastened together at their ends by smooth pins or ball and socket joints acting as hinges. Plane truss: A truss consisting of members which lie in a plane and are loaded in the same plane is called a plane truss. Ex: Roof truss, bridge truss, etc. Space truss: A truss made up of members not lying in the same plane is referred to as space truss. Ex: Electric power transmission tower, microwave tower, etc. Page 4 TRUSSES CONTENTS : 1. Introduction. 2. Plane truss. 3. Statical determinacy and stability of trusses. 4.
