for tensile tests, specimens were prepared with a diameter of 6 mm and a gauge length of 30 mm. Shear punch test (SPT) is a small-specimen testing method (SSTM) in which the results are exhibited through the load–displacement diagrams similar to those acquired from uniaxial tensile test[12]. SPT is based on exerting shear force on a slice of material via a punch with an appropriate diameter. Through......
the relevant research is insufficient. In this work, an experimental study on the seismic behavior of RC shear walls after being exposed to fire was presented. 2 Test program 2.1 Specimen details Five shear... previously recorded.3 Test results 3.1 Failure mode of specimens A view of specimens at failure is given in Fig.4. For shear walls (N4T0 and N4T0-D) unexposed to fire, the phenomena at failure on both......

Simulation of Fiber Pushing-out Test张亚芳Faculty of Civil Engineering,Guangzhou University摘 要:The stress distribution on the failure progress of fiber pushed-out test was studied. A numerical program, developed by meso-damage mechanics, was adopted to simulate the whole failure process of interface debonding and fiber pushing out. From the simulation......
