<p>Due to the large number of underpasses in the Netherlands that have to be assessed, a project at the Delft University of Technology in cooperation with Royal HaskoningDHV was started. Research was conducted into the automation of the structural assessment of existing reinforced concrete underpasses in the Netherlands. The developed Automated Structural Assessment Tool (ASA Tool) consists of an analytical model and a 2.5D FEM model. The analytical model uses traffic load distribution following the Guyon-Massonnet-Bares method for bending and a method based on <i>fib </i>Model Code 2010 for shear. The script-based 2.5D FEM model uses 2D shell elements and performs a linear elastic analysis. The input and output can be linked to a database for assessment of large batches. Sensitivity analyses showed that in-plane load distribution following <i>fib </i>Model Code 2010 combined with vertical load distribution according to EN 1991-2:2003 results in underestimated shear forces.</p>

A quasi-static analytical model for needle bearing was established base on the rolling contact theory and the force analysis of needle bearing,and the model was caculated by computer program.Conclusions are drawn as follows by analysis of needle bearing load distribution in different misalignment,different load,different clearance,different speed,different crown drop of needle:work of bearing would be influenced if misalignment so big,the influence of misalignment must be considered when the engineer determine the clearance of beearing, it’s rotational speed has small influence on the load distribution of bearing ,reasonable choise of crowning of needle could be enhanced the lifetime of needle bearings.
