compression load
1.The reasonable axial compression, load angle and the ratio of stirrup of special-shaped columns are gained from the contrastive analysis.
2.This paper introduced the test method for plane strain fracture toughness of powder metallurgy HIP moulding metallic beryllium at room temperature It was concluded that for K IC testing of brittle beryllium, fatigue precrack could be prepared by tension compression cyclic load with a load ratio P min / P max of -3 The average K IC value of tested beryllium at room temperature was 9 91MPa·m 1/2 , standard deviation was 0 73MPa·m 1/2
3.This paper reviews the research and application of high performance asphalt pavement, introduces the design concept of high performance asphalt pavement system ( MoPPPPW&H and TRL), i.e, considering the secondary compression of traffic load and using the general methods of Marshall-type design, describes the key points of design and flow process, in site construction properties and practical engineering projects so as to provide a new way for high performance asphalt pavement research of China.
4.After a series of confined compression tests and dead-load in-situ tests in a engineering project were carried out for GRS, comprehensive and systematic researches were launched on the compressibility effect on GRS caused by same damage factors such as lateral stress unloading, dry shrinkage, saturation;
