APPROXIMATE CALCULATION METHOD OF THE BENDING MOMENT CONSIDERING GEOMETRIC NONLINEARITY IN ARCH BRIDGES

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

table of maximum bending moment shear force and support reaction for simple bridges

tables of maximum bending moment, shear force and support rections for simple bridges with span lengths ranging from 2m to 250m are presented.loadings are selected according to the specification given by the highways and transportation ministry of iran. the procedure of using the tables is shown by means of an example.

An identification method for short hanger tension of arch bridges

The hanger tension is crucial in arch bridges and the fundamental frequencies of short hangers are significantly affected by the flexural rigidity. In order to measure the hanger tension considering the flexural rigidity, the Additional Mass Method (AMM) is proposed in this paper. The tension and flexural rigidity can be calculated by the measured frequencies without and with the additional mas...

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...
