| Outline and Purpose of the Course | This course will cover the structural design theory of concrete building structures (reinforced concrete buildings, steel-reinforced concrete buildings, prestressed concrete buildings, etc.), based on material theory and structural mechanics theory relating to concrete and steel. It will explain the rules for the composition of hardened concrete under multi-axial stresses and applications for methods of structural analyses such as the finite element method. Lectures will explain the relationship between properties related to durability (such as concrete carbonation and salt erosion) and concrete mixing, and describe measures to extend the lives of buildings and ensure durability in aggressive environments. | ||
| Course Goals | To understand and use the structural design theory of concrete building structures (reinforced concrete buildings, steel-reinforced concrete buildings, prestressed concrete buildings, etc.), based on material theory and structural mechanics theory relating to concrete and steel. To understand the rules for the composition of hardened concrete under multi-axial stresses, and be able to apply it in methods of structural analyses such as the finite element method. To understand the relationship between properties related to durability (such as concrete carbonation and salt erosion) and concrete mixing, and be able to propose measures to extend the lives of buildings and ensure durability in aggressive environments. | ||
| Schedule and Contents |
Ultimate Limit State of Concrete Structural Members (3 classes) These classes will explain the basic knowledge and design methods relating to material ductility capacity that are considered to be necessary for high earthquake-resistance in concrete structures. Specifically, these classes will describe basic theory relating to the effect of confined concrete on mechanisms resisting bending in plastic hinge regions of beams and columns, and basic mechanisms resisting shear forces. Additionally, these classes will introduce methods of calculating deformability of members based on ultimate flexural strength, ultimate shear strength, and the ratio of these strengths used in performance evaluation design method. Long-term Properties of Concrete Structural Members (3 classes) These lectures will explain cracks and deformation, which can cause problems for concrete members under long-term loads. Methods for assessing creep and dry-shrinkage of concrete and the influence exerted by such factors on individual member and a whole structure will be described. Earthquake-resistance Evaluation and Strengthening for Existing Reinforced Concrete Buildings (3 classes) These classes will explain seismic strengthening design and the construction methods used, based on the methods and results of evaluating earthquake-resistance capacity of existing reinforced concrete buildings. Evaluating buildings' strength will be described in detail, based on determination of the aging deterioration of a building based on concrete carbonation; irregularity in elevation and in plan of a building; and the deformability and ultimate strength of members. New upgrading construction methods will also be introduced. Post-Earthquake Diagnosis of Damaged Reinforced Concrete Buildings (3 classes) These lectures will describe methods for determining the degree of emergency risk and of classifying the level of damage as methods for diagnosing a damaged reinforced concrete building after an earthquake. The objectives, positioning, specific procedures, and theoretical background of the evaluation methods will be explained with examples of buildings damaged by past earthquakes. Prestressed Concrete Structures: Design and Theory (3 classes) These lectures will explain the behavior of prestressed concrete (PC) structures under service load and in earthquakes. PC structural member analyses, and structural design theory that uses such analysis, will be described. These lectures will describe analyses of the response of PC building structures to seismic excitations based on PC structure's deformation and stress redistribution based on concrete creep; mechanisms that resist bending and shear; and the hysteretic restoring force characteristics of members. They will also explain the structural design of PC buildings. |
