ANALYSIS OF SOIL-STRUCTURE INTERACTION OF A REINFORCED CONCRETE TOWER
|
抄録（英）：
A vast amount of earthquake response records of an observation tower are used together with microtremor records to investigate various aspects of the dynamic behavior of the soil-structure system. It is found that separation of the soil from the structure occurs under large dynamic loads, leading to changes in the predominant frequency of the system. With regard to its practical applicability, a linear sway-rocking model is applied for numerical modeling of the soil-structure system. The effect of separation and soil nonlinearity is represented with softening coefficients, which are evaluated by comparing real and simulated structural response. The influence of each of these factors on the softening is investigated. An empirical relationship between the peak ground velocity and the soil spring constants for earthquake excitation of different magnitude is presented.
