Class Objectives
/Class Outline
Students acquire the abilities to
1. Arrange the experimental results to evaluate the validity of the experimental results.
2. Logically explain their findings in each experiment in comparison to the theories in oral test and report.
3. Solve the problem with group discussing from an understanding of their role and consider the phenomena spontaneously.
(1) Concrete
1) Physical properties of materials and production of RC beam
 To design mix proportion of concrete and conduct appropriate modification of the mix proportion from the results of tests for slump and air content. To evaluate workability of concrete from the state of fresh concrete.
2) Bending/shear test of RC beam
 To understand and explain a stress-strain relationship of concrete, the behavior of chloride ion diffusion into concrete and carbonation of concrete. To calculate the stresses of tension and shear reinforcements in an RC beam and the flexural and shear strengths of the RC.
(2) Soil
1) Consistency limit and Consolidation Tests
 Under the consistency limit tests, liquid limit and plastic limit tests will be conducted. These are basic soil properties and it is used to classify the soils.
Consolidation test results are useful to determine the settlement with time for civil engineering structures.
2) Direct Shear and Tri-axial tests
 Tri-axial test is generally used to determine the shear strength parameters, cohesion and friction angle of cohesive soils under drained and un-drained situations. In general, direct shear test are to determine the shear strength parameters of cohesion-less soils. Shear strength parameters are very important to determine bearing capacity of soil, and stability of slopes.
(3) Structural Engineering
1) Experiment for bending deformation of a beam
 You would be able to understand the beam theory by experimental method which be carried several loads testing and observing deformation behavior of a simple beam.
2) Test of material characteristics of steel.
A phenomenon of a stress-a distortion relation, elasticity and plasticity of steel can be understood and explained by doing a tension test of steel and observing deformation behavior.
(4) Hydraulics
Students should be able to understand Uniform flow, Rapidly varied flow, Gradually varied flow in Open Channel, Steady flow through a pipe, Laws of friction and Energy losses.
1) Resistance law for open channel flow and Energy loss in pipe channel flow
To discriminate subcritical, critical and supercritical flows in open channels, and to explain the phenomena in open channel flows.
To understand the resistance law and the energy losses in pipe flows, and to explain the phenomena in pipe flows.
(5) Environmental preservation
1) Survey of River Water Quality
 Water samples in a river are collected and analyzed to understand procedures, principles, and methods of water qualities for water environments. 
Class Schedule (1) Concrete (Kawai, Ogawa, Riya)
1) Physical properties of materials and production of RC beam
2) Bending/shear test of RC beam
(2) Soil (Hata, Hashimoto, Ho)
3) Consolidation test and consistency test
4) Direct shear test and triaxial compression test
(3) Steel structure (Nakarai, Ario)
5) Experiment for bending deformation of a beam
6) Relationship between strain and stress
(4)Hydraulics (Kawanishi, Hibino, Nakashita, Uchida)
7) Laws of friction and water surface profiles in open-channel flows and energy losses in pipe flows (laminar and turbulent flows)
(5) Environmental preservation (Ozaki, Kindaichi)
8) Survey of River Water Quality

The eight experiments will be carried out and an oral test will do before the experiment.
Students should submit report after every experiment. 
The texts and references necessary for each experiment will be given at the first class (guidance).

Other This year, some issues will be handled online(including face-to-face), so please check the schedule in advance and confirm with the person in charge of the issue.
By the way, for the guidance of 6/16, carefully read and confirm the common material group under the "Documents at the time of guidance on June 16 (Tuesday)" folder on bb9, and confirm the group composition, the issue implementation date, and the person in charge of the issue. After that, please proceed with the group-based implementation day under the folder for each assignment. 
Please fill in the class improvement questionnaire which is carried out on all classes.
Instructors will reflect on your feedback and utilize the information for improving their teaching.
