__STRUCTURAL ANALYSIS II__

**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.
