Segmented arch or continuous arch technique? A rational approach
This study aims at revising the biomechanical principles of the segmented archwire technique as well as describing the clinical conditions in which the rational use of scientific biomechanics is essential to optimize orthodontic treatment and reduce the side effects produced by the straight wire technique.
متن کاملDevelopment and Practical Application of a Lifetime Management System for Prestressed Concrete Bridges
A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...
متن کاملHeuristic optimization of prestressed concrete precast pedestrian bridges
This paper deals with the economic optimization of prestressed concrete precast pedestrian bridges typically used in public works construction. These bridges are made of a precast concrete beam that integrates an upper reinforced concrete slab for the pedestrian traffic. The beam has a U-shape cross-section. Typical span lengths range from 20 to 40 m and the width ranges from 3.00 to 6.00 m. Th...
متن کاملFailure Modes Analysis of Stone Arch Bridges
A destruction test based on the bridge safety appraisal is one way to verify the failure law of an actual bridge. In this paper, a stone arch bridge in a 1:10 scale model and with a span of 60 m (namely, an arch bar of the same length as the object of test) has been tested, methods of its whole test and loading process introduced, and ultimate bearing capacity, deflection and development rules ...
متن کاملHydraulics of River Flow Under Arch Bridges
IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera tion, often necessary, is the length of the bridge. In certain circum stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...
