In this study, we attempted to investigate the spatial gradient distributions of thermal shock-induced damage granite with respect associated deterioration mechanisms. First, shock experiments were conducted on specimens by slowly preheating high temperatures, followed rapid cooling in tap water. Then, investigated computed tomography (CT) and image analysis techniques. Finally, influence temperature gradients was discussed. The results show that induced can cause more than slow cooling....
ABSTRACT One of the main ways to improve seismic performance coupled shear walls is develop replaceable coupling beams with higher performance. In this paper, comparative tests on cast‐in‐place wall leveraged friction (CPCW‐LFCB) and CPCW reinforced concrete (CPCW‐RCB) were conducted, influence LFCB deformation characteristics CPCWs was analyzed. First, specimens CPCW‐RCB CPCW‐LFCB both in a bending mode their failure modes showed characteristic “strong piers weak beams.” At same time, two...
Abstract In order to improve the efficiency of friction dampers, a shear‐type response‐amplified damper (RAFD) was proposed, which utilized lever mechanism amplify shear displacement and increase sliding distance pairs. Cyclic loading tests were conducted on 12 RAFD specimens evaluate effects machining processes, materials, protocols, bolt pretension mechanical performance specimens. The results showed that with NAO brass pads exhibited plump hysteresis loops, bearing capacity, effective...
In the present study, we tried to understand spatially distributed damage in sandstone samples under coupled stress-freeze-thaw (SFT) conditions. Firstly, uniaxial compressive stresses (i.e. 0 MPa, 10 20 and 25 MPa) were applied samples, then freeze-thaw (FT) cycles (0, 8, 16, 24) performed on uniaxially stressed realize SFT coupling. Next, real-time CT scanning was conducted observe induced damage. The total porosity introduced quantitatively evaluate degree. local variation, with distance...
Due to the important role of nuclear power plant containment in prevention leaks, it is great necessity study model's loading mechanism and gas distribution. Most models previous studies were small size, with a maximum ratio 1:4. Moreover, focused on pressure thermal-pressure coupling have not been examined. In this study, we take Langfang's 1:3.2 model as object. Before experiment, simulation air-vapor mixed working medium was performed absolute loaded 1.0 MPa. The temperature at several...
As a semi-active control device, the magnetorheological (MR) damper has received much concern for its great controllability, quick response and lower input power. However, problem of liquid leakage is produced after long-term service, severely affecting performance service life. To solve this problem, paper proposes fully vulcanizing consolidating viscoelastic material, cylinder barrel piston rod, which replaces traditional dynamic seal with static develops new leak-proof MR damper....
With the rapid development of industrial automation and power electronics, requirements for electrical contact materials are increasing. However, traditional encountered significant bottlenecks in terms performance enhancement production environmental friendliness. Therefore, this paper proposes a new material design idea that utilizes π-π interactions between graphene compounds with conjugated structures order to achieve uniform dispersion metal matrix thus enhance composites. Based on...
This study investigated the effects of freezing temperature under freeze-thaw cycling conditions on mechanical behavior sandstone. First, sandstone specimens were subjected to 10-time treatments at different temperatures (−20, −40, −50, and −60 °C). Subsequently, a series density, ultrasonic wave, static dynamic tests carried out. Finally, P-wave velocity, stress–strain curves, uniaxial compressive strength, elastic modulus, energy absorption discussed. The results show that density slightly...
Compared with the traditional reinforced concrete columns, concrete-filled steel tubular columns a better restraint effect of tube on core showed higher bearing capacity and ductility under static loads. However, except loads, are commonly exposed to extreme dynamic loads including earthquake, explosion, impact. The study behavior is extremely significant ensure their safety against such In this article, polyvinylidene fluoride piezoelectric smart sensor was proposed monitor axial impact...
