ASM is a statistical model applied to match contours of non-rigid object. The actual contour may much different from the initial contour and the result is likely to converge to an error contour. Kalman filter is adopted to track the current frame for the prediction and acts as the initial state of the ASM, and then applies the ASM to correct the contour of the object. Experimental results show that the method proposed in this paper allows the model to converge to the target contour quickly and accurately. It has good stability and robustness.
“strong beam and weak column”is the main failure states of reinforced concrete frame structure in the earthquake.This paper studies the influence on the virtual cross-section bearing capacity on extremity of frame beam in reinforced concrete in experiment through the project example and analysis of finite element method,such as slab’s reinforcement,the rigidity of frame beam, the rigidity of orthogonal beam and so on.Exploring the mechanism of slab and frame work together to determine the width of effective flange,which provides references for structural design and engineering application.
Stability of the road embankment is the foundation of the highway normal operation and maintenance, so there is strict requirement of road subgrade settlement for the highway. This article uses the gray theory to predict Cheng Chi high embankment construction settlement and builds a predicted model and tests the model’s accuracy. The results of settlement prediction are under the limits, so the stability of the road subgrade is good. This dynamic prediction method can be used on prediction of the settlement of high embankment and it’ll direct the operation and ensure the maintenance safety.
Curved girder bridge can adapt to the complex needs of road, so it applies more and more. Because prestressed curved girder bridge is spatial structure, its deformation under load, prestress etc is very complicated. If ill-considered, it will cause accidents as cracking of beam body, too large transverse displacement and bearing disengaging etc. In this paper, by analysis of engineering examples, using ANSYS finite element analysis software modeling and calculating, we get the deformation law of small and medium span curved girder bridge under deadweight and prestress, and the law has guiding significance and practical value on design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
