With the increase of the height and structural complexity of the long-span cable-stayed bridge tower, the buffeting response of the free-standing tower and its control become one of the key issues in bridge engineering. In this paper, Sutong Bridge, a long-span cable-stayed bridge with a main span of 1088 m is taken as the engineering background. 3-dimensional wind turbulence field for the free-standing tower is simulated according to the measured specification spectrum, the buffeting response of the free-standing tower under the action of strong wind and its control using MTMD are studied based on ANSYS. The control effect on buffeting of the free-standing tower of long-span cable-stayed bridge and the key MTMD parameters are investigated. Results show that the influences of the MTMD parameters including the number of TMD, mass ratio, frequency bandwidth and damping ratio are not identical. The MTMD with reasonable parameters can greatly decrease the buffeting displacements for the free-standing tower of the cable-stayed bridge, and therefore effectively control the buffeting of the main tower. Results can provide references for wind-induced buffeting control of the free-standing tower of long-span cable-stayed bridges. [ABSTRACT FROM AUTHOR]

Asset return's distribution is not unique, it will generate Knightian uncertainty. This paper analyzes the relationship of investor information set and Knightian uncertainty. Then based on shadow probability theory, a mapping which describes risk and this kind of uncertainty on asset return, and a new asset pricing model with ambiguity is constructed. Measuring Knightian uncertainty of Chinese stock market, the result shows an decreasing trend on this uncertainty which is smaller than the U.S. Moreover, an empirical study of asset pricing with ambiguity reveals that Chinese investors are showing a preference for this uncertainty.
