  1. Based on extensive investigation of construction technique history of chinese ancient buildings, the structure method, structure developing history and seismic behavior of chinese ancient timber structure buildings are analyzed in several respects of the structural system and form. through a series of experiments on constituent parts of chinese ancient timber building structure, including the tests on the corbels and brackets called dougong subjected to low cyclic reversed loadings, the tests on the wooden frame using the tenon - mortise joints as connections of column and beam subjected to low cyclic reversed loadings, the tests on vibration isolation effect of friction and slippage between column footing and their socle base, and a series of shaking table tests on a chinese ancient timber structure palace building mode under artificial earthquake at serving conditions, destroyed conditions and reinforced conditions, many valuable results of structures such as moment - curvature hysteretic loops of dougong structure and tenon - mortise joints under low cyckc reversed loadings, the static function, the seismic performance, energy dissipation, vibration reduction, energy - loss mechanism, nechanicalmode and failure mode were studied. aplenty of valuable parameters of the structure system were obtained, such as the natural period of structure, vibration modes, damping ratio, factor of vibration isolation, oscillate amplitude of ineitial accebration, velocity and displacement, magnitude of slippage, and the mechanism of structure failure and collapse etc. based on these research, the complete analysis of ancient timber structure under earthquake were carried out in which including mechanism analysis method, calculating mode, strength analysis of members and joints, strengthening methods for serving damaged ancient timber structure buildings were also taken into account

  4. The continuous damping control rule using adaptive controller based on artificial neuro network ( ann ) is researched. this rule has no strict demand for the bandwidth of the damper, the cost of damper is low, the practicality is good

    論文研究了基於神經網路自適應控制的半主動懸掛連續阻尼控制策略，這種阻尼控制策略能降低對阻尼器件帶寬的要求，降低成本，增強半主動懸掛系統的實用性。
  5. Artificial ground motions, for their optional and statistic properties, are regarded as an important form of input for structural time history analysis in contrast to the actual records. present simulation methods which are mostly derived from spectra - compatible technique do well suit for single - damping - ratio - spectra simulation, but the simulation precision is not satisfactory when the spectrum is n ' t the object spectrum

    目前常用的反應譜擬合技術能對給定單一阻尼比反應譜進行較好的擬合，但在目標譜以外其它阻尼比反應譜的擬合上有較大誤差，這就是反應譜擬合技術中存在的多阻尼比反應譜擬合問題。
  6. Then the explicit finite - volume method for the two - dimensional steady navier - stocks equations is studied. in order to prevent odd - even decoupling of the solution and oscillations near the shock waves, artificial dissipation is added. local time step, residue averaging, enthalpy damping and multi - grid method are used to accelerate the convergence during the five - step runge - kutta explicit time marching
