Most research on computer vision (CV)-based vibration measurement is limited to the determination of discrete or coarse mode shapes structure. The continuous edge structure in images has rich optical features, and thus, by identifying tracking movement structure’s edge, it possible determine high-resolution full-field without a preset target. present study proposes CV-based method shape identification using subpixel detection techniques. Firstly, Canny operator applied each frame video...
The indirect method for bridge modal identification based on the response of moving vehicles has attracted widespread attention in recent years. However, most existing studies only focus simply supported bridge, while continuous girder bridges are widely used practical engineering. Therefore, this study proposes an frequency bridges. First, mode shape formula equal-span beam is deduced using three-moment equations, and analytical solution vehicle vibration via vehicle–bridge coupled theory....
Intrusion analysis and incident management remains a difficult problem in practical network security defense. The root cause of this is the large rate false positives sensors used by Detection System (IDS) systems, reducing value alerts to an administrator. Standard Bayesian theory has not been effective regard because lack good prior knowledge. This paper presents approach handling such uncertainty without need for information, through Dempster-Shafer (DS) theory. We address number but...
Composite box girders with corrugated steel webs (CBGCSWs) are used worldwide owing to their light self-weight, high efficiency of prestressing application, and reasonable distribution shear force bending moment. An improved composite girder (ICBGCSWs) has been recently introduced further reduce the dead weight improve its durability. Because innovative ICBGCSW emerged as a new structure, very few studies have conducted on dynamic characteristics. In present study, theoretical analysis was...
Nanozyme is a kind of mimetic enzyme possessing unique properties nanomaterials and catalytic functions natural enzymes. The nanozymes have the characteristics high efficiency good stability are widely utilized in medicine, chemical industry, food, agriculture, environment. This laboratory experiment designed for third-year undergraduate students who background chemistry or material science. involves synthesis, characterization, performance, application copper doped cerium oxide...
Reissner’s principle (R-P), which considers the effect of all secondary shear stresses on deformation, is proposed for analyzing elastic behavior a composite box girder with corrugated steel webs (CBG-CSWs) under restrained torsion. The cross-sectional geometrical properties were calculated considering accordion web (CSW), and formulas warping normal stress derived. Based this, governing differential equation torsion CBG-CSWs was established based R-P. In comparison widely used Umanskii’s...
Modal identification of bridges based on the responses moving vehicles, termed as indirect method, has drawn much attention in recent years. This method been proven to be capable identifying bridge frequencies and mode shapes feasibility research. However, presence additional factors such vehicle speed road surface roughness, it is difficult identify high-order high-resolution bridge. The authors previously proposed a tractor-double-trailers model time–domain subtraction obtain relative...
Prestressed concrete (PC) girders with corrugated steel webs (CSWs) have received considerable attention in the past two decades due to their light self-weight and high prestressing efficiency. Most previous studies were focused on static behavior of CSWs simple beams CSWs. The calculation deflection is an important part analysis structures. However, very few been conducted investigate full PC or bridges no formulas are available for estimating under loads. In addition, experimental work...
The friction factor between 6061 aluminum alloy and die material (SKD61) are determined at different temperatures by using ring compression test which carried out on a testing machine. Mechanical properties fiction then applied to the finite element analysis of wheel forging for elevated temperature. Maximum load, effective stress temperature distribution forging, finie analysis. Finally, parts formed machine under conditions
This two-part paper presents a generic methodology for assessing the short-term voltage stability (STVS) of power systems dominated by inverter-based resources (IBRs). approach introduces concept generalized damping (GVD) quantifying STVS from both global and local perspectives. It leads to model-independent stability, system strength, capability dynamic devices support during transience. Part 1 this focuses on deriving system-wise (sGVD) index its applications. The sGVD is defined as decay...
In order to reasonably analyze the influence of shear deformation corrugated steel web on natural vibration frequency PC continuous box-girder bridge with webs, first, element stiffness matrix webs is derived by using energy variation principle. Second, according matrix, solution program for calculating multispan uniform cross-section considering shearing effect compiled MATLAB software. The correctness frequencies calculated software verified measured constructed and value ANSYS 3D...
With the advantage of high strength, lightness, and good environmental resistance, glass fiber reinforced polymer (GFRP) pultruded profile is regarded as an innovative way that has been used in infrastructure over last few decades. However, some disadvantages also limited its widespread application practice, including relatively low elastic shear modulus deformability due to buckling failure. To overcome these disadvantages, composite structure systems are proposed, such GFRP‐concrete...
