Course Description

Fundamental concept of static and dynamic stability of large-scale structures such as bridges is to be introduced in addition to the way to keep/improve their safety and to evaluate their performance. Basic concept of structural stability and its application and technical subjects to improve safety will be lectured systematically. Furthermore, the practical solutions to the subjects are to be introduced to assure the safety of structures.


Grading will be evaluated by written examination, reports and attendance.

Course Goals

The class aims to cultivate the understanding of static and dynamic stability problems for structural system and make understand the methodology to clarify the limit state. To get knowledge on countermeasures to assure the stability which is applicable to practical design and manufacturing will be also required.

Course Topics

Theme Class number of times Description
Elastic Stability under Static Loading 7 Stability of Structures and Failures
Basis of Structural Stability
Elastic Buckling of Columns
Elastic Buckling of Beams & Frames
Elastic Buckling of Plates
Elasto-plastic Buckling
Buckling Analysis
Basic theory of dynamic stability and its application 7 The stability around the equilibrium points based on the state equation of motion in which the nonlinearity of external, damping and restring forces are taken into account. Wind-induced vibration of a square prism (Galloping) and 1dof system with nonlinear spring will be introduced as practical examples. Chaotic motion of a pendulum subjected to periodic external force is also explained as an introduction of chaos theory.
