This paper validates the effectiveness of modeling approach based on finite element analysis shaking table tests, establishing models for both a base-isolated structure and hybrid designed to address overturning issues in diesel engine building nuclear power plant. By using Incremental Dynamic Analysis (IDA) method, fragility resistance was conducted isolation systems. study demonstrates that base scheme, which incorporates additional dampers, effectively enhances structure’s reduces...
Base isolation technology, as a mature seismic mitigation method, demonstrates potential for enhancing margins in nuclear power plant structures. This study investigates the performance of isolated and non-isolated models diesel generator building through shaking table tests. A 1/8-scale structural model was designed tested under operational safety ground motion (SL-1), ultimate (SL-2), beyond design benchmark (BDBE) excitations. finite element considering different tensile compressive...
Abstract BTW1/Q345R composite plate not only has the advantages of high strength and wear resistance, but also helps to reduce energy consumption production cost. This paper proposes a novel rolling process based on corrugated rolls for preparation wear-resistant steel plates. In order analyze study microstructure, mechanical properties plates after rolling, techniques such as electron backscatter diffraction (EBSD) were used. The results indicate that obtained through with roll 72 cycles...
In this paper, the shaking table tests and finite element analyses were conducted on traditional thermal power plant main building with BRBs, respectively. The differences in torsional resistance between two structural systems studied, suppression effect displacement field distortion of plane consisting crane tracks through adding BRBs was discussed. study shows that after adopting a buckling-restrained brace building, damage response structure under an earthquake can be reduced, occurrence...
In this study, detailed finite element analysis was conducted to examine the seismic performance of square and circular hollow steel braces under axial cyclic loading. Finite models were constructed using ABAQUS (FEA) software validated with experimental results from previous papers expand specimen’s matrix. The influences cross-section shape, slenderness ratio, width/diameter-to-thickness ratio on hysteretic behavior compressive-tensile strength degradation studied. Simulation parametric...
Reinforced concrete frame bent structure (RCFBS) is a popular structural pattern in industrial power plant, while it behaves poor seismic performance several previous earthquake accidents. This study adds buckling restrained brace (BRB) the experiment model to improve of main structure. However, for such structures few BRBs just are permitted set into its body due limits process layout. To reinforced work aims how BRB and examine role
The reinforced concrete main building structure of a 600 MW thermal power plant is taken as the background project. buckling restrained brace (BRB) used energy dissipation element to optimize seismic design original frame bent-brace structure. Through time history analysis and three kinds shock absorption structures, their performance under rare earthquakes compared. results show that BRB can effectively control displacement response at weak layer, improve internal force distribution...
Short-time Fourier transformation (STFT) has been widely recognized as an intuitive time-frequency analysis method. However, its application in building structures is constrained by low accuracy of low-frequency recognition short data. Accordingly, all-phase chirp-z (AP-CZT) proposed for frequency structures. Specifically, the autoregressive (AR) model, which a order determination algorithm, used to solve problem data length limitation process. Subsequently, algorithm based on absolute...
