Reliability Approach to the Design, Construction and Use of Natural Draught Cooling Towers
Structures or structural elements should be designed and constructed such they are suited to their intended use. But principles for the design, construction, use and maintenace are changing evolutionary. It is due to fundamental research and the progress in technology.
Application of GPS technology to measurements of displacements of high-rise structures due to weak winds
Abstract Global positioning systems (GPS) have been developed for military purposes like single-point positioning and navigation. The first non-military applications have been made for geodetic purposes with base-line measurements using differential methods. We introduce GPS technology as an alternative measurement method of displacements when high-rise structural systems are monitored. In this paper, two tests to evaluate the accuracy of the measurements using GPS are presented. Then the evaluation of ability of GPS to measure small movements of the Stuttgart TV-tower and the industrial chimney of Opole power station due to weak winds are also given.
Reliability Analysis of Discrete Dynamic Systems under Non-Stationary Random Excitations
In this paper we shall describe an approach to the study the reliability of structures modeled as linear discrete dynamic systems which has been designed to withstand nonstationary random excitations. Ne shall discuss this problem upon consideration the following four steps:
