Abstract

The safety concepts form the basis of modern structures design and assessment codes. The detailed information about the structural deformations can help to determine the health of these structures, as well as to evaluate whether such deformations are the same as those the structure was designed to tolerate. This thesis investigates an integrated monitoring system for the estimation of the structural deformations behavior of ordinary and smart structures. Three different surveying techniques (precise leveling, one and two total stations measurement techniques) are presented to evaluate the deformation behavior of structural members. The comparison study between the surveying and structural techniques for computation the structural deformations is introduced and discussed. These techniques are applied to measure the structural deformation of reinforced concrete beams, vertical wall and El­Derasat Bridge. The results of the practical measurements, calculations and analysis of the interesting deformation using least squares theory and computer programs are presented. The influence of auto­correlations on the estimated parameters, and the variances are also shown. Finally, the three used surveying techniques with a special mathematical and adjustment models can be used in monitoring the structural deformations with high accuracy in the ordinary structures. Moreover, the surveying techniques can be motorized to give the continuous monitoring for ordinary and smart structures.
