Design of RCC Structure

Course Objective:
The purpose of this course is to provide the students knowledge and skill for design of different elements of a building structure using reinforced concrete. The course focuses on Limit State Methods of Design and the students will learn to use output of Structural Analysis to design different elements according to the codal provisions and detailing of the reinforcement. The course also includes key features of Seismic Building Code and provisions of ductile detailing in reinforced concrete structures.
