Students will be familiar with methods of structural performance assessment, compliance criteria and design rules for traditional and engineered building types. Students should be able to evaluate the quality of structural systems, to interpret the performance of masonry and steel structures under horizontal action, to derive appropriate models and to decide upon the applicability of equivalent or simplified ones. Students get introduced to passive vibration control technologies for the reduction of seismic and wind induced building response. Students will be trained the principles and application of seismic isolation and supplemental damping devices, gain insight into the design provisions, modelling requirements and practical realization of base isolation.
Students will be informed about on-going research projects and recent code developments which are linked to the course topics and options for further graduation (master thesis). Training of student’s ability to apply methods mirroring the current state in natural hazard and risk assessment will be qualified. Students will be able to apply modern software tools to transfer buildings into dynamic models and to evaluate the seismic response characteristics: In dependence on design situation and performance directed concepts; they will be guided to identify design defects, and to evaluate the appropriateness of strengthening measures.
Structural performance of traditional and engineered building types (L)
Reinterpretation of observed response for different building types; design principles, compliance criteria and structural solutions for traditional (masonry) and engineered (steel) type structures; building assessment criteria for strengthening; theoretical basis of seismic isolation and passive supplemental damping; mechanical characteristics and modelling of isolators and dampers; practical examples.
Application of base-isolation to unreinforced masonry and RC structures (E, P)
Search for typical building representatives of the target regions (home countries of the participants); derivation of structural layout and simplified models of representative building types; modelling and assessment of masonry structures applying equivalent frame approach; determination of characteristic building response parameters; damage prognosis; designing the isolation system; comparison of building response and performance.
Publications relevant for the course and exercises will be available on MOODLE.
