Module Title:Structural Design and Analysis I
Credits: 10
NFQ Level:8
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: Lectures, Practicals, Projects
Module Aim: 1) To develop an understanding of the stress and strain behaviour of elastic and elastoplastic materials under axial, flexural and torsional loads. (2) To develop the skills required to analyse the force distributions on encastré and continuous beams and statically indeterminate plane trusses. (3) To develop an understanding of behaviour of struts (4) To introduce the concepts of real work, virtual work and strain energy and apply them to finding deflections and analysing statically indeterminate beams and trusses. (5) to extend the learner’s knowledge of the application of structural loads; (6) to enable the learner’s to design reinforced elements (7) to enable the learners to design steel beams, columns and trusses; (8) to enable the learners to use computer applications in structural design. 9) To understand the implications of long and short term sustainability of selecting a particular material , construction type and method with a view to sustainability
