This course, targeting graduate students that have acquired knowledge relating to basic architectural structures, covers structural design and material selection, ways of thinking about component and joint design, geometric nonlinear theory for performing spatial structures design, optimization theory, oscillation theory for performing seismic isolation and damping structure design, equivalent linearization, earthquake-resistant design, plasticity theory for making diagnoses and improvements, load-carrying capacity calculations, foreign design standards and their background, as well as exercises in specific structural planning that applies each theory.
Through the above tasks, students experience a selection of the tasks involved with real structural design work, and understand the meaning of studying more specialized structure and disaster prevention courses. Students aspiring to study structural design are strongly encouraged to take this course.
By the end of this course, structural design students will be able to learn the following;
1)Ethics and sense for the structural design, the way for collaboration with archirtect
2)Design of spatial structures understanding the basic theories of geometric non-linearity and optimal design method
3)Design of seismic isolation and response controlled structures based on basic structural dynamics and equivalent linearity
4)Seismic design and retrofit based on basic plastic theories and ultimate strength evaluation
5)Member design based on overseas standards
