Abstract

This article deals with the problem of determining the resistance of end-plate connections. A nonlinear FEM model of the joint was constructed in order to predict its carrying capacity. A standard code procedure was done as well. The analyses have been done to assess atypical end-plate joints designed and constructed as a part of roof structures.

Abstract

The paper presents a concept and realization of monitoring system for the Silesian Stadium in Chorzow. The idea of the system lies in fusion of structure monitoring with a calibrated numerical FEM model [1]. The inverse problem is solved. On the base of measured selected displacements, the numerical FEM model of the structure combined with iterative method, develops the current snow load distribution. Knowing the load, we can calculate the forces and stresses in each element of the structure and thanks to this we can determine the safety thresholds and asses the owner. Test results and conclusions are presented.

Abstract

This paper describes influence of cargo lorry traveling at high speed under a lightweight footbridge on the structure vibrations. The unsteady CFD simulations were performed to obtain aerodynamic load functions on the footbridge. These loads were introduced to nonlinear structural dynamics transient calculation to obtain footbridge response. The influence of aerodynamic forces was evaluated in terms of pedestrian comfort and safety. Parametric study of the influence of vehicle speed, structure clearance, cabin deflectors and distance between lorries grouped in convoy is also presented.
