Science of Concrete Structures 1

Concrete structures are highly public and are required to remain sound for a long period of time, so rational and thorough consideration is required at the design stage. In particular, concrete structures are required to meet structural performance requirements such as safety and usability against large external forces, and as a civil engineer, it is essential to understand how to design them. .
Therefore, this lecture will explain the mechanics and design theory of reinforced concrete structures. First, a lecture will be given on the mechanical properties of structural materials "concrete" and "reinforcing steel." Next, we will give a lecture on the mechanical behavior of members subject to bending, which is the most basic element in reinforced concrete structures, and will also provide a detailed explanation of the design philosophy based on the current design method (limit state design method).

The main purpose is for students to learn the mechanical properties of materials used in reinforced concrete members and the outline of the design of members that undergo bending. To this end, students will be taught to understand the limit state design method and the mechanical phenomena that lead to the failure of reinforced concrete members.

1. Students will be able to understand the material properties of concrete and reinforcing steel (stress-strain curves, strength) and analyze the behavior and theory of reinforced concrete under bending (before cracking occurs).
   ⇒ Check understanding level using Assignment 1
2. Students will understand the behavior and theory of reinforced concrete structures subjected to bending (after cracking occurs), and apply this to calculation of the balance reinforcing bar ratio necessary for determining bending failure and ultimate bending strength (single reinforcing bar rectangular cross section). I can do it.
   ⇒ Check understanding level using Assignment 2
3. Students will be able to understand the fracture behavior of reinforced concrete due to bending force, and will be able to apply this to the calculation of ultimate bending strength (double reinforced rectangular cross section/T-shaped cross section).
   ⇒ Check the level of understanding using Assignment 3
4. Students will be able to understand the elastic behavior of reinforced concrete due to bending force and apply it to the calculation of bending stress in the limit state of use (arbitrary cross section/single reinforcing rectangular cross section).
   ⇒ Check the level of understanding using Assignment 4
5. Students will be able to understand the behavior and theory of reinforced concrete members subjected to bending, and analyze the usability and safety of reinforced concrete using performance verification methods (service limit state, ultimate limit state).
   ⇒ A final test will be used to assess whether you have a sufficient understanding of the content of Assignments 1 to 4.

(1) Assume that you have achieved your goal with a score of 60 points or higher on the final exam.
(2) Submit all four assignments (required condition for taking the final exam)
