AIM:
To make students aware of how structural resolutions become important in realization of
architecture design concept. At this stage, students shall be exposed to forces, moments, and
resolution that are to be resolved. Concepts of structures, and enable students to solve basic,
simple problems.
OBJECTIVES:
 To enable a student to understand the effect of action of forces on a body and the concept
of equilibrium of the body through exercises.
 To determine the internal forces induced in truss members due to external loads by working
out problems.
 To calculate the sectural properties (centroid, moment of inertia, section modulus and radius
of gyration) for various sections by working out problems.
 To study the struss – strain behaviors of steel and concrete due to axial loads and to
determine the stresses and strains developed in solids due to external action through select
problems.
 To drive the relationship between elastic constants and solving problems.
