Great Span Anomalistic Viaduct Seismic System Research

The human science and technology progress is impelling the civilized and society's unceasing development. Since 20th century , humanity obtains in the natural sciences and humanities each domain the achievement is before quite several centuries sum totals. The bridge construction profession also entered along with the advance in technology tide for a brand-new time.City scale expansion and prosperity request bridge design many considerations to its in artistry, as well as to its in environment influence. Bridge esthetics also receives more and more common people's value. After on century World War II, each place of the world had the foresight unparticular, the bridge constructor has made the varying degree endeavor in the bridge esthetics theory and the practice reverse side, also has obtained the huge achievement. Our country's bridge esthetics enterprise also robotized in the recent years takes, and developed rapidly, theory and the achievement of all quarters are great. But the bridge is one kind of special surmounts, we can not just par attention on its value in beautification function, the bridge structure function potency (or the function esthetics) should be the most important consideration or should be simultaneously considered.Based on the above situation, this article (esthetics of modeling) studies the bridge through bridge static esthetics characteristic and the dynamic esthetics characteristic. Bridge static esthetics mainly is Research Bridge modeling esthetics, butte bridge esthetics of dynamic mainly is through the bridge dynamic performance and the mechanical analysis result.After analyzed the bridge esthetics universal principle, I carry on the sublimation to the bridge form, drew the conclusion to think bridge esthetics had to create the live form, the organic form and the free form ,when research bridge static esthetics. Especially in proposed the bridge must create the live form, I proposed may through observe and study human and animal's activity and the structure designs even more conforms to mechanics principle and has the vigor the form. Finally utilizes the theory through the example which introduced to carry on the analysis thus specifically to explain the theory.When research bridge kinetic esthetics, I first analyzed the functions, which have possibly been able to affect in bridge modeling esthetics the bridge dynamic performance factor, then to listed the model to carry on the mechanical analysis. The analysis results are divided into three parts: One, the distortion and the distortion curve, two is the oscillating curve and the model, three is the vibration resolving. Research these three parts separately, utilized esthetics theory and the mathematics esthetics and the physical esthetics of theory which front elaborates and so on. Finally obtains the conclusion explanation the relations between the modeling esthetics theory as well as modeling esthetics and the dynamic esthetics.
