Module Aim: |
The aims of this module are: 1.) to develop the skills required to analyse the force distributions and deflections in 2 dimensional frames; 2.) to develop an understanding of the plastic theory of structures in relation to beams, 2d frames and reinforced concrete slabs; 3) to develop an understanding relevant to civil engineering structures of the structural dynamics of beams; 4) to develop the skills to use computer programs for the analysis of beams and 2d structures. 5) to extend the learner’s knowledge of foundation design, portal frame type building including wind loading analysis and the design of composite floor beams. 6) to have an understanding of the the long and short term implications of material section and construction type and method |
