| Schedule and Contents |
Introduction of design theory of civil infrastructure,2times,Design theory of civil infrastructures is introduced. The concept and significance of design, objective of design, characteristics of civil infrastructures, flow of design process, mechanical design, multi-level decision making are discussed. Engineering ethics are also explained. Introduction of load,3times,Design loads for civil infrastructures are introduced. The characteristics and classification of design loads are explained and their quantitative expression is discussed. Especially statistic characteristics of random loads, i.e. seismic load and wind load, are explained. Prediction of earthquake ground motion and earthquake response of structure,2times,Methods for predicting earthquake ground motion are introduced based on the theories of earthquake mechanism and ground vibration. Equation of motion for the single degree of freedom system and its solution are also explained in order to estimate earthquake response of structure. Design methods for infrastructures are interpreted on the basis of theories of elasticity and plasticity. Characteristics of natural wind and aerodynamics of structures,2times,The characteristics of natural wind and strong wind are explained and process of design wind for structures is discussed. And various aerodynamics (vortex-induced vibration, galloping, flutter, buffeting, and etc.) acting on structural section with various geometric shape and their generation mechanism are explained. Limit state of structure and reliability analysis,3times,The outline of structural safety analysis is introduced for serviceability, ultimate and fatigue limit of structures. As for uncertanities in various actions to structures and the resistance of structures, the design methods such as allowable stress method, limit states method with partial safety factors will be discussed in conjunction with reliability analysis. Seismic design, wind resistant design, optimal design, and landscape design,3times,Seismic design, wind resistant design, optimal design and landscape design for various structures, including long span bridge |
