In the fourth semester, the subject Design of Steel Structures provides students with the fundamental principles of steel design. The subject Design of Reinforced Concrete Structures focuses on the analysis and design of R.C.C. components such as slabs, beams, columns, and footings using the Limit State Method in accordance with IS 456:2000. Upon completion of this course, diploma students will develop a comprehensive understanding of the structural behaviour, analysis, and design principles of R.C.C. members. They will be equipped with the necessary technical knowledge, analytical competence, and practical design skills required to undertake structural design tasks effectively in the construction and infrastructure industry. | ## Course Outcome: After Completion of the Course, Student will able to: | No | Course Outcomes | RBT Level | |------|-------------------------------------------------------------------------------------------------------------------------------------------|-------------| | 01 | Interpret IS Code provisions for Limit state R.C.C.
