2.7 Shrinkage
- Theoretical value: (a=35, : Maximum Shrinkage Strain Ratio)
- The process of finding 'a'
1. Arranging excel data
2. Finding 'a' with using a grapher program
(Converting Excel data into graph shape)
(Standardization of graph through regression analysis)-회귀분석을 통한 그래프 평균화
(Finding 'a' with using shrinkage equation)
3. Finding 'a'
strength obtained from tests of the double
axial loads P notation refers to the value
calculated by dividing .
Shear Strength
-An intersecting point of the shear stress axis and the line
which contacts uniaxial compressive circle and tensile circle
in Mohr's stress test.
2. METHOD OF CONCRETE
STREN
concrete refers to concrete tie that compression is strong but strengthen reinforcing rod to strengthen seal because is weak to seal.
(1) RC method of construction
Fig 7. RC structure.
If define RC method of construction breifly, because rubing cement and sand, gouge the interval and call method of construction to inlay reinforcing rod.
This method of construction that is called alias rein
♧ 역사적 배경
콘크리트의 역사를 보면 B.C. 300년경 이집트에서 석회석을 이용한 몰탈이 시작된 이후 A.D.126년에 로마의 펜티온 신전의 돔이 콘크리트 구조물로 축조되었으며, 18세기 이후에서야 영국인 Joseph Aspin 등에 의해 포틀랜드 시멘트가 최초로 제작되어 오늘날 시멘트콘크리트의 시초가 되었
concrete construction takes 30~35% if money takes in framed constructions, concrete is dense in construction fee.
- Stronger stress resistance in compression than other materials.
- Good Durability, Fire endurance, Water resistance, Insulation of sound
- Higher compression strength than other materials
- No limitation in shape or size(can form to any shape)
- Can make a particular strengt
strengths in Pixar. HR strategies of PIXAR are divided into 4 factors: Company’s strategies, Company’s Environment, Company’s Characteristics and Company’s capabilities. The third part is analyzing the company Pixar based on SWOT which is strengths, weakness, opportunity, threat. To compare other companies, we analyzed other two animation companies. In the conclusion, we’d like to see w
in the range of theory, and the value from the second experiment is 0.16 which also comes under the range of theory. In case of specimen no.1, there was an error of 12.6% but the Poisson's ratio is highly appropriate. From this, we can analogize the Poisson's ratio has nothing to do with strength, but is related to the materials.

1. 한중 콘크리트
개요
최근 국내에서도 콘크리트 시공기술의 향상으로 영하의 동절기에도 구조물의 소요강도 및 내구성을 만족시킬 수 있는 콘크리트를 시공하기에 이르러 사계절 시공이 가능하게 되었다.
일반적으로 영하의 기온에서 콘크리트를 타 설하게되면 초기에 동결되어 동해를 입게되
