AR2351 DESIGN OF STRUCTURES III L T P/S C 3 0 0 3AIM:The course is structured to teach the design of Reinforced concrete column, footings andretaining walls and to introduce the concept of pre-stressed concrete.OBJECTIVES: To use limit state design for the analysis and design of columns. To enable the learning of design of structural elements like footings, retaining walls andmasonry walls. To understand the principle, methods, advantages and disadvantages of pre stressedconcrete.CONTENT:UNIT I LIMIT STATE DESIGN OF COLUMNS 10Types of columns Analysis and Design of hort !olumns for A"ial, #nia"ial and bia"ialbending #se of Design aids.
