Special Services

 
ES-Consult has since its establishment completed several tasks related to important civil and structural works and has also carried out many special assignments in the category of applied sience. A very important part of the activities of the firm has been assistance and technical consultances to building- and infrastructure owners.
Here follows descriptions of a series of ES-Consult's special services.

 

 

Finite Element Analysis

Introduction

ES-Consult has experience in analysis of many types of structural members and machine components concerning strength, lifetime, and properties in service.
ES-Consult has sophisticated Finite Element software at its disposal. It enables the company to carry out detailed analyses of complex structures and structural elements. A Finite Element analysis may consist of an investigation of structural parts with respect to rupture, deformations, vibrations or fatigue failure caused by repeated actions.
In cases where Finite Element analysis has appeared to be insufficient, ES-Consult has often succeeded in developing efficient calculation methods for the solution of the actual problems.

Special Assignments

For the company IN-MIX Ltd., ES-Consult has carried out an analysis of an agitator for a coal silo in a power plant.
The analysis included a dimensioning of the agitator with respect to rupture and fatigue and also a determination of the deformations and the lowest natural frequency. The analysis involved a modelling of various complex three-dimensional structural members.
The project of the Øresund Bridge between Denmark and Sweden had to include an investigation of the consequences for the bridge of ship collisions due to the heavy ship traffic in the sound. The purpose of the analysis was to optimize the bridge substructure so that a possible ship impact would not have catastrophic consequences for the bridge and for the traffic on the bridge.
The investigation has been carried out by making a Finite Element model of the entire ěresund bridge. This model made it possible to make a realistic assessment of the vibration level of the bridge as well as a determination of the permanent deformations of the structure after a ship collision.

Other Perspectives

The structures and the loads on them may be so complex, that calculations alone are not sufficient to assess the response of the structure. In such cases the design must be verified after the construction by monitoring and observing the properties of the structure.
ES-Consult has gained experience both in the planning and management of such measurements and in the subsequent interpretation of the results of the measurements. Here it is advantageous to organize the measurements in data bases with the aim of comparing the results with the calculations. As a result, a greater knowledge about the properties of the construction can be gained.
