Abstract Based on the reconstruction and expansion project of an expressway, a set rapid construction technology for integrated erection fully prefabricated rigid frame bridges is proposed, which solves problems unmatched work efficiency each working face in conventional bridge erectors long period traditional suspension assembly technology. This method realizes this type highly urbanized areas...

In order to improve the management and control level of bridge construction understand real-time dynamics in real time, a set cloud 3D visualization information system is created based on Internet platform. view characteristics high precision great difficulty corrugated steel webs bridge, software B/S (browser/server) architecture developed help managers know site structure state more intuition...

A quick group search optimizer (QGSO) is an intelligent optimization algorithm which has been applied in structural optimal design, including the hinged spatial structural system. The accuracy and convergence rate of QGSO are feasible to deal with a spatial structural system. In this paper, the QGSO algorithm optimization is adopted in seismic research of steel frames with semi-rigid connection...

The goal of template tracking is to estimate the transformation parameters that define the motion of the planar template. Typically, the transformation parameters encode linear transformation based on homographies with 8 degrees of freedom, which allows them to track rigid motions of the template. However, when it comes to tracking surfaces that undergo non-rigid deformations, deformable transf...
