안녕하세요.....
무기질징크 도장후 마찰계수에 대해서 문의 하셨는데....
관련자료가 있어서 몇자 적어봅니다... 도움이 되심 좋겠네요
시험기관 : *********
시험목적 : 무기질 징크 도장후 마찰 접합면 마찰 시험
시험방법 : AISC APPENDIX A
사용도료 : Carboline Korea Carbozinc 11 (Thinner 10% 사용)
도장후 시험일자 : 12일
건도막두께 : 5.4 Mils
Slip Co Efficient : 0.62
SLIP TEST PROCEDURE
The test specimens were positioned in the frame to allow for 0.125" or slip before bearing contact with the 7/8" rod occurred. Each specimen was aligned so that the entire bottom surface of the two outside plates was in contact with the base plate. The spherical head of the testing machine is on the base plate.
The compressive LOAD is applied at a rate of approximately 20 kips per minute. All samples are tested to a travel of at least 0.05 inches (unless there is reason to believe that there will be a sudden equipment). An X-Y recorder is used to simultaneously record slip and LOAD values. This product slipped in a curve similar to "C" in the Research Concil on Structural Connections Specification, Appendix A, Section 3.4
The average slip LOAD for the first five sample was 60,354 pounds.
Base on the above test th co-efficient of slip is 0.62
* 1kip = 1000 pound
