In this study, the effects of ambient temperature on horizontal mechanical performance isolated rubber bearings were investigated using high-speed reciprocating loading methods. A comprehensive series 54 experimental trials are performed full-scale (900 mm-diameter) isolation bearings, encompassing a range temperatures (−20 °C, 0 and 23 °C), shear pressures (50%, 100%, 250%), frequencies (0.20 Hz, 0.25 0.30 Hz). Because compression-shear tests conducted at high velocities (specifically,...
Objective This study aims to examine the prevalence of myopia among pupils in different residential areas (city center, nearby suburbs, and far suburbs) grade levels (lower, middle, upper), analyzing social behaviors risk factors guide early intervention. Methods A cross-sectional survey was conducted with elementary students across various regions Nanjing. total 2,342 valid questionnaires were collected. Univariate multivariate logistic regression analyses used identify assess for their...
Electrical substations and vital components, e.g., disconnect switches, experienced severe damage that caused blackouts during past earthquakes. To improve the seismic resiliency of power grids use probabilistic decision-making frameworks, comprehensive fragility data for different substation equipment are needed. The objective this study is to investigate performance develop component system curves a critical component: switches. vulnerability two common switch types was evaluated...
Cultural relics are precious properties of all humankind, the damage which is nonresilient. In previous earthquakes, stored cultural have shown poor seismic performance, so effective methods urgently needed. However, due to various restrictions, traditional damping not suitable for in Palace Museum. An efficient method, composed silicone damper and connecting elements, proposed protect these relics. This novel device very convenient install no change or move original structures It kinds new...
The yield performances and failure mode of reinforced concrete (RC) columns, which are critical structural to the design research engineering structures, have a significant impact on dynamic response, performance level, seismic ductility. traditional empirical theoretical method used predict leads large dispersions in most cases. To better estimate RC this paper developed novel neural network method. Empirical models determine input parameters by analyzing factors that affect rationality...
The purpose of this study is to investigate the attenuation effect pile barrier in blocking seismic surface waves by using theoretical and numerical methods. First, we derive dispersion characteristics barriers embedded soil from perspective periodicity theory explain that such periodic can attenuate when main frequencies fall into band gaps barrier. Second, composed different inclusions are discussed, it suggested preliminarily scatters with low stiffness density more conductive mitigate...
To investigate the bearing behavior of symmetrical full-scale different strength concrete filled double skin steel tube (CFDST) stub columns, 19 specimens were designed, considering slenderness ratio (λ); compression core and sandwich (fcki, fcko), thickness inner outer tubes (ti, to); diameter (Di, Do); tensile (fyki, fyko) as main parameters. Nonlinear constitutive models for constraint effect adopted, a finite element (FE) model was established using ABAQUS software. By comparing results...
Adding energy dissipation devices to reinforced concrete (RC) frame structures is a commonly adopted structural enhancement in seismically active regions. In this paper, state-of-the-art seismic performance assessment applied typical fixed-base RC structure designed based on the current Chinese code. Two additional enhancements, including equipping buckling restrained braces (BRB) and designing as base-isolated structure, are investigated. Nonlinear response history analyses were performed...
As one of the most important buildings in Forbidden City Beijing, Qin-An palace was initially built 1535 Ming dynasty. The is mainly constructed with large wooden frame structure (L-22.25 m × W-19.68 H-16.67 m) asymmetric double eaves and thick masonry infill wall north face. To better understand seismic performance itself related non-structural components provide useful suggestions for relic protection from earthquake damages, a scaled 1:5 architectural model prototype kind typical sample...
Important buildings, such as hospitals and nuclear power facilities, must have basically intact pipe systems to function effectively after an earthquake. To study the seismic fragility failure mechanisms of different typical bracing system types, this paper conducts a comprehensive series 34 monotonic cyclic loading tests on four distinct configurations bracing. The bearing capacity performance ductility components are evaluated thoroughly by using area (energy) corresponding yield...
We analyze the global and local uncertainties of ground motion-macroseismic intensity conversion equations derive new probabilistic relationships between macroseismic peak motion parameters (peak acceleration velocity) for western China based on assumption that values are randomly distributed each MMI level, bounded by a normal distribution. For this purpose, strong database consisting 37 moderate- to large-magnitude earthquakes occurred in 1994 2017 is employed along with corresponding...
In order to acquire the hysteretic behavior of asymmetrical composite joints with concrete-filled steel tube (CFST) columns and unequal high beams, 36 full-scale were designed, CFST hoop coefficient (ξ), axial compression ratio (n0), concrete cube compressive strength (fcuk), (fyk), beam, column section size taken as main control parameters. Based on nonlinear constitutive models double broken-line stress-hardening model steel, by introducing symmetric contact element multi-point constraint...
