METHODS OF INVESTIGATING THE OPERATIONAL BEHAVIOUR OF A STRUCTURE SUFFERING FROM A NUMBER OF DISORDERS

项目名称：	METHODS OF INVESTIGATING THE OPERATIONAL BEHAVIOUR OF A STRUCTURE SUFFERING FROM A NUMBER OF DISORDERS
摘要：	IN A BRIDGE WITH OPERATIONAL DISORDERS, THE KNOWLEDGE OF THE NEW MECHANICAL CHART WOULD HELP TO OBTAIN A BETTER EVALUATION OF ITS RESIDUAL STRENGTH. A REAL CASE WAS SELECTED: A BRIDGE WITH TWO RIBS AND THREE CONTINUOUS SPANS, AND A CRACK IN THE IMMEDIATE VICINITY OF THE INTERMEDIARY BEARINGS. AFTER A DETAILED STUDY OF THE DISORDERS, MEASUREMENTS WILL BE MADE UNDER STATIC LOADING AND WITHOUT LOADING. EXPERIMENTAL INFLUENCE CURVES WILL BE PLOTTED FOR PRESSURES ON THE BEARING SURFACE AND FOR DEFORMATIONS OF PARTICULAR SECTIONS. AN ATTEMPT WILL BE MADE TO ESTIMATE THE NEW STIFFNESS OF THE DIFFERENT MEMBERS AND TO DEFINE PLASTIC PIVOT PINS FOR THE CORRESPONDING FISSURED SECTIONS. THE OBJECTIVE OF THE RESEARCH IN 1979 IS TO TEST THE VALIDITY AND SENSITIVITY OF THE METHOD PROPOSED ABOVE. IN THE LONG TERM THE LIMITS OF SUCH A METHOD WILL BE DEFINED TOGETHER WITH OTHER METHODS APPLICABLE IN OTHER CASES.
