In fact, to achieve the element “death” effect, the selected “dead elements” were deactivated by multiplying their stiffness matrices by a reduction factor, which caused the element loads associated with the deactivated elements to be zeroed out in the load vector and the element strains were also set to be zero[5-6].
According to the statistic data, mean wind is defined as logarithmic equation and turbulent wind is simulated by Kaimal fluctuating wind power spectrum and harmony superposition method.

In order to study the vibration response regularity of the subgrade in the case of high-speed, domestic and foreign scholars have made extensive research.For example, the tests about dynamic stress and sinking were carried out by Sunaga et al[1];the indoor tests about bearing capacity increased and settlement reduction after subgrade reinforced by geogrid were carried out by Goebel et al[2];the wheel load tests for subgrade with different stiffness were carried out by Leykauf[3]; Xuehua Chen and Zhihong Nie et al[4,5] studied the dynamic response law of Qinhuangdao-Shen yang Passenger Special Line by on site test.
It provides the scientific measured rest and accumulated engineering practice data for further theoretical research.

Global trends aiming at production costs reduction and energy and resource saving urge manufacturers to design new and improve the existing lockup devices for safety fluid couplings.
From the data given in Figure 4 it is seen that the lockup device having a cylindrical working chamber (Curve 1) meets these requirements to the fullest extend possible.

The bridge section picture after installing ITMD (mm) The parameter of MTMD is one of the important factors which can affect the control effect, according to basic data of the selected bridge, the damping ratiois determined, and the angular frequency can be calculated by the first-order symmetrical vertical bending vibration frequency of the bridge deck.
Defining vibration reduction efficiency factor as (1) Where and are respectively the RMS values of buffeting response of the centre of main span without dampers and with dampers.
