| 摘要： | This paper presents the main results obtained from field tests carried out in four sites of three recently built elevated viaducts in Mexico City. The main objectives of the tests were to determine and assess the structural response of elements located at representative sections of the viaducts. Focus was given to the identification of main static and dynamic properties, the measurement of the lateral displacement of the column-footing assemblage under monotonically increasing loads, and the study of the soil-structure interaction of the assembly. The field tests ranged from ambient vibration measurements to applying horizontal and vertical loads to the structure by means of pulling cranes and both parked and moving vehicles. The tests were aimed not only at providing experimental evidence to support the general assumptions used by the design firm, and to make the proper adjustments if deemed necessary, but to contribute to the body of knowledge with respect to elevated viaducts built by means of precast posttensioned members. |
