Full Unit-wise Syllabus

Unit I – Soil Mechanics

Introduction to Soil Mechanics. Concept of Safe bearing capacity. Types of soil. Distribution of upward pressure in different types of soil (No mathematical Calculation).

Unit II – Loads and Load Distribution

Types of Loads - Gravity, Wind, Dead, Live Load. Introduction to structural systems, Load flow and distribution. Concept of load distribution for structural systems and overall stability like a) One way slab b) Two-way slab c) Arches e) portal frames f) Space Structures. Determinate and Indeterminate structure (no numerical problems /calculation).

Unit III – Shear force and Bending moment of Beams

Beams and supporting conditions. Types of supports. Shear force and bending moment for simply supported, cantilever and over hanging beams (point load and uniformly distributed load).

Unit IV – Bending and Deflection in Beams

Theory of simple bending. Stress distribution at a cross section due to bending moment and shear for Rectangular, I and T sections. Concept of Flitched and Castellated beams (no numerical problems / calculation). Basic factors causing deflection in Beams, relation between slope, deflection and curvature. Determination of deflection and slope for simply supported and Cantilever beams using Double Integration Method and Macaulay's method (point load and uniformly distributed load).

Unit V – Columns

Short and long columns. Concept of elastic stability. Euler’s theory. Assumptions and load carrying capacity of columns with different end conditions. Concept of effective length. Slenderness ratio. Limitations of Euler’s theory. Rankine’s formula.
