COURSE OBJECTIVES

• To enable students to design miscellaneous and complex structural elements manually and suing software
• To give basic understanding of earthquake-resistant design and evaluation/assessment and
retrofitting of concrete structures and pre-stressed concrete.

COURSE LEARNING OUTCOMES (CLO)


CLO: 1. to report on the concepts of earthquake-resistant design, retrofitting and pre-stressing of RC structures including their stepwise procedures for simple cases.
CLO: 2. to design miscellaneous and complex RC structural members under different conditions (i.e. loadings, boundary etc) by manual calculations.
CLO: 3. to seek clarification and justify (i) step-wise procedures for earthquake-resistant design, retrofitting, pre-stressing and (ii) manual gravity designs of miscellaneous and complex RC members.
CLO: 4. to develop (i) finite element model of simple RC structure under seismic loadings and its structural detailing using computer programs (e.g. ETABS/SAFE/AUTOCAD) and (ii) models for design of miscellaneous & complex RC members using software.
