The seismic performance of an electric power system is crucial for maintaining the functionality urban communities following earthquake. In thermal plants, RC frame–shear wall structure plays a key role in providing resistance to main building’s longitudinal structural system. This study presents results series pseudo-dynamic tests on two-span, four-story model with scale 1/8. prototype was seven-story, seven-bay from workshop large plant. cracking process, yielding sequence, hysteresis...
In areas with high seismic activity, enhancing the performance of subway station structures is paramount importance. This paper presents a novel approach involving application an ECC-BFRP (Engineered Cementitious Composite Basalt Fiber Reinforced Polymer) composite layer to reinforce central columns stations situated in loess site. To evaluate effectiveness this reinforcement method, three-dimensional finite element model structure, accounting for soil-structure interaction (SSI) effects,...
Proper characterization of asphalt concrete mixtures with respect to the changes in dynamic modulus (DM) applied loading frequency and test temperature is a key task for pavement structural design. This phenomenon generally described through use master curve, which an important input mechanistic empirical design tools. In current abbreviated DM testing protocol, given AASHTO TP-79-09, limiting maximum value, estimated Hirsch model, used constrain upper portion curve function. However,...
Abstract Using indexes based on engineering properties is among the ways to evaluate quality of an asphalt concrete mix in terms its resistance fatigue cracking. These typically are developed measuring or binder a laboratory test. Among such tests, semicircular bend (SCB) test has shown potential as promising determine mixtures. In work presented, this was explored extensively proper performance identifiers from Numerous tests were conducted effect composition SCB results. A major index...
Due to the high compressive strength of steel fibre-reinforced reactive powder concrete (SFR-RPC), a higher degree prestressing is available for SFR-RPC beams. Hence, more slender structural component can be designed, which reduce self-weight, usable area and, potentially, costs. However, in comparison with conventional reinforced-concrete beams, there are fewer studies on post-tensioning beams subjected shear failure. In this study, series tests four large-scale (one beam and three beams)...
Abstract Oxidative aging stiffens asphalt in the pavement, raising brittleness, cracking potential, and deterioration of pavement serviceability. Mechanical testing long-term aged concrete laboratory has shown elevated stiffness, higher failure load (peak load), reduced fatigue resistance. Among mechanical tests used to evaluate mix resistance flexibility is semicircular bend (SCB) test. This study was conducted determine how properties mixes compare with those from short-term tested under...
Based on an underground structure located at a soft loess site in Xi’an as the engineering background, this paper investigated seismic response and damage model of subway stations using large-scale shaking table test, considering different characteristics ground motions. The quantitative analysis acceleration subsidence were subjected to earthquake excitations; based experimental results corresponding analysis, development distribution structural studied, mechanism structures area under...
Adding reclaimed asphalt pavement (RAP) into mixes is a common practice and has many merits such as reducing costs emissions. In recent decades, state highway agencies have embarked on investigating with high RAP content. As the content increases, understanding how well binder blends virgin becomes more crucial. Lack of knowledge much residual actively during production one reasons preventing full exploitation materials. Obviously, amount aged blending affects properties mixes. A study was...
This paper presents an experimental study that discussed the influence of fiber ratio, resin type, and different rib forms on shear strength failure mechanism glass fiber-reinforced polymer (GFRP) bars. Shear testing can be considered for material quality, structural design, safety in use purposes. Test results reveal epoxy winding GFRP bars are 10–15% 6–10% higher than vinyl extruded bars, respectively. The sensitivity variance was 0.12 type 9.67 form. Higher uncertainty effect form Within...
