CE3602 STRUCTURAL ANALYSIS II

L T P C: 3 0 0 3 | Total Hours: 45 Periods

COURSE OBJECTIVE

• To learn the method of drawing influence lines and its uses in various applications like beams, bridges and plane trusses and to analyse arches and suspension bridges

UNIT I: INFLUENCE LINES FOR DETERMINATE STRUCTURES

Introduction to moving loads, Concept of Influence Lines, Influence lines for reactions in statically determinate structures - Influence lines for shear force and bending moment in beam section - Calculation of critical stress resultants due to concentrated and distributed moving loads - Influence lines for member forces in pin jointed plane frames.

UNIT II: INFLUENCE LINES FOR INDETERMINATE BEAMS

Muller Breslau's principle - Influence line for support reactions, shearing force and bending moments for indeterminate beams - propped cantilevers, fixed beams and continuous beams.

UNIT III: ARCHES

Arches - Eddy's theorem - Types of arches - Analysis of three-hinged, two-hinged and fixed arches - Parabolic and circular arches - influence lines, rib shortening- Settlement and temperature effects.

UNIT IV: SUSPENSION BRIDGES AND SPACE TRUSSES

Analysis of suspension bridges - Unstiffened cables and cables with three hinged stiffening girders - Influence lines for three hinged stiffening girders - Introduction to analysis of space trusses using method of tension coefficients.

UNIT V: APPROXIMATE ANALYSIS OF FRAMES

Approximate analysis for gravity loadings - substitute frame method for maximum moments in beams and columns - Approximate analysis for horizontal loads - portal method and cantilever method - assumptions - axial force, shearing force and bending moment diagrams.
