Research On Prestressed Concrete Continuous Bridge Layout Of Tendons In Interaction And Parameterization

As the software and hardware for the rapid development of computer technology, computer technology change quickly,bridge engineering computer aided design (bridge CAD)with a new face of rapid development has entered a phase. Design achievements realize optimal progressively, design speed was improved significantly design means was more perfect. Just so that people was released from many repeat heavy physical and mental, greatly increased labor efficiency so that the traditional means of bridge design and design method has produced significant changes. It become one of a mark in bridge design technology modernization because of greatly contributed to it's progress.This article takes prestressed concrete continuous bridge layout of tendons in interaction and parameterization as the research object, based on practice of Luzhou TuoJiang No. 1 double track bridge. The first step is estimating tendons area of the element following the method of tendons design. Using the thought of structural optimization design to estimate the tendons area and it improve estimation precision of tendons area. The second step is laying vertical tendons in interaction and parameterization after achived the tendons area, mean while constituting a friendly user interface, realizing fast action with tendons laying and entering. The last step is realizing automatic drawing construction picture finally by determineing horizontal steel tendons with human-computer interaction and operating AutoCAD 2006 database with ARX2006, after completing vertical steel tendons layout and finite element structural checking computation.Practice to show that this system has important practical significance on improving the prestressed concrete continuous beam designing efficiency and drawing precision.
