This study presents a finite element (FE) model, the accuracy of which is verified by comparison between numerical and test results. The calibrated model used to investigate influence vertical arrangement masonry material infill walls on seismic performance reinforced concrete (RC) frames through pushover analysis time–history analysis. lateral capacity, interstorey drift ratio, plastic hinge distribution structures discussed. It was found that damage with irregular more serious than bare...
This study presents a finite element model to investigate the bidirectional seismic behavior of masonry infill walls. The test data are utilized verify numerical model. comparison between analytical and experimental results indicates that can successfully predict failure mode, stiffness, strength wall. Based on model, effects aspect ratio (height length), slenderness thickness), out‐of‐plane (OOP) response wall with in‐plane (IP) damage explored. Considering ratio, wall, OOP without IP is...
Total focusing method (TFM) has improved resolution and accuracy over traditional ultrasonic phased array technology.In this paper, an advanced parallel architecture in field programmable gate arrays is suggested to significantly accelerate the imaging efficiency of TFM.Several techniques are investigated, including real-time concurrent calculation for time flight, generation multiple pixels, Hilbert transform pixels array.This achieves computation flight times each pixel double TFM...
Masonry infilled RC frames are one of the most common structural forms, damage which, in earthquake events, usually cause serious losses. The determination seismic performance target is key foundation performance-based evaluation and design for masonry frames. In this paper, an extensive database experimental tests on loaded in-plane direction collated. According to crack propagation elastic-plastic characteristics frames, process divided into four stages, then criteria states (DS) proposed....
Pile groups are designed to sustain complex loads in various engineering. During the design of a pile group, obvious group effect should be considered for closely spaced groups. However, by different scholars varies, which makes it hard engineers consider group. In this study, finite element (FE) method is proposed advance our understanding variations effects developed researchers, based on concept soil–pile relative stiffness. The relationship between stiffness and normalized lateral...
A high-pass cut-off frequency in filtering is critical to processing strong-motion records. The various procedures available nowadays are based on their own needs and not universal. Regardless of the methods, a visual inspection filtered acceleration integration displacement required determine if selected filter passband appropriate. better method use traversal search combined with frequency, which traditional method. However, this inefficient unsuitable for massive In study, convolutional...
The damage pattern of masonry-infilled reinforced concrete (RC) frame structures in earthquake events is complicated, and understanding the detailed failure behavior these modeling it accurately has been a challenging task. In this paper, extended finite element method (XFEM) introduced to reproduce arbitrary cracks initiating propagating masonry units, combined with interface elements model various behaviors RC frames. Within analysis program FEAP, user subroutine adopted for incorporation...
In order to study the influence of friction wheel parameters and loading eccentricities on horizontal bearing characteristics pile-wheel hybrid foundations, numerical calculation models foundations offshore wind turbines in heterogeneous soil were established by using ABAQUS finite-element software. The results show that with increase diameter, height, density decrease eccentricity, capacity increases. With diameter height wheel, change amplitude load gradually weakens, indicating there is...
The efficiency of metro rolling stock maintenance directly affects the safety and capability train operation in main line.Aiming at optimization problem scheduling (RSMS) metro, a multi-objective mixed integer nonlinear bi-level programming model was presented this paper to improve as well availability planning horizon.In model, systems, timetable line capacity crews are taken into comprehensive consideration.To solve optimal solutions quickly, static variable ordering heuristics according...
The over-strength coefficient is one of the key factors for seismic safety a structure. For RC frames, infill wall may improve lateral bearing capacity, while demand increases as well, which leads to unexpected performance an infilled frame in past earthquakes. Therefore, it necessary systematically study effect frames from point capacity and demand. In this paper, 36 structures with/without walls are designed, corresponding finite element modelings, considering in-plane out-of-plane...
