Bridges and buildings are vulnerable to dynamic forces such as winds and
earthquakes. These structures are complicated and the response to these
forces cannot be easily obtained. This lecture first introduces
fundamental theories of dynamic structural analysis for the single degree
of freedom structures, then moves to more advanced theories for the multi-
degrees of freedom structures. Most of the actual structures have multi-
degrees of freedom. Second, as an application of this theory, lateral
vibration of a footbridge induced by pedestrians is introduced. Third,
seismic design method is explained based on the design specification for
road bridges in Japan. This lecture is given in Japanese and English.
English is the most commonly used language in the world business and
industries and is also essential to engineers as well.
The lectures are given in Japanese and English. It may be difficult to
understand new ideas and theories in English. Try to read the handouts
carefully before and after lectures, and do many exercises by yourself.
