Structural Mechanics part 2 is an academic subject whereupon students acquire basic knowledge and skills not only for calculating internal forces, but also for determining lines of influence and displacements in statically indeterminate planar structures. Students, also gain knowledge in the area of sustainability and building dynamics of systems.
The course covers the methods for calculating the above-mentioned statically indeterminate systems: force method, displacement method, mixed method, combined method and finite element method (FEM), sustainability and building dynamics of systems. During the exercises appropriate case study problems are solved and thus is illustrated the material presented in the lectures. Students acquire skills to solve the most common problems in practice by independently solving individual assignments. The acquired knowledge and skills shall be verified by two tests and in dialogue with the professor in order to authenticate course assignments.
Course assignments include research on the following static schemes:
Assignments №1 - 3 - framework for a force method - internal forces generated by:
Course assignment №1 – external load.
Course assignment №2 – temperature influence.
Course assignment №3 – supporting structure succumbs (falsework succumbs to …)
Course assignment №4 – shifting from an external load into statically indeterminate system.
Course assignment №5 – statically indeterminate system - truss efforts by external load.
Course assignment №6 – framework under displacement method – internal forces by external load
Course assignment №7 – continuous beam – shear efforts (forces)
Course assignment №8 – frame resistance under deformation method
Course assignment №9 – dynamics of systems of one or two degree of freedom system – „d” – method
Course assignment №10 – calculating earthquake structure
