授業の概要・目的 This course provides the knowledge of the structural planning and design for civil infrastructures.
The structural morphology, aesthetics and case studies of structural design that satisfies “utilitas, firmitas and venustas” are given. Then we discuss what the holistic structural design should be.
Fundamentals of the reliability of structures based on the probability and statistics are given. Emphasis is placed on the reliability index and the calibration of partial safety factors in the LRFD design format.
到達目標 The course provides the idea of structural planning (conceptual design and embodiment design), the structural design based on the reliability and the performance design.
授業計画と内容 Structural Planning(2 lectures)
Structural Planning of civil infrastructures is introduced. The concept, significance of planning, characteristics of civil infrastructures are discussed. Practical planning process of a bridge is explained.

Structure and Form(3 lectures)
The excellent examples of modern structural design are introduced from the viewpoint of the structural system and the urban design. Then the importance of integrated design of urban infrastructure as a place of human activites and how the design should be lectured.
The bridge types, for example, girder, truss, and arch etc. that have been regarded individually, are lectured as an integrated holistic concept from the view point of the acting forces to understand the structural continuity, symmetry and the systems. Furthermore, the methods of the operation of structural form are given.

Structural Design and Performance-based Design(3 lectures)
Design theory of civil infrastructures is introduced. The allowable stress design method and the limit state design method are explained. The basic of earthquake resistant design is discussed based on the dynamic response of structures.

Random Variables and Functions of Random Variables(1 lecture)
Fundamentals of random variables, functions of random variables, probability of failure and reliability index in their simplest forms are lectured.

Structural Safety Analysis(3 lectures)
Limit states, probability of failure, FOSM reliability index, Hasofer-Lind reliability index, Monte Carlo method are lectured.

Design Codes(2 lectures)
Code format as Load and Resistance Factors Design (LRFD) method, calibration of partial safety factors based on the reliability method are given.

Feedback: Assessment of the Level of Attainment(1 lecture)
