Quick Test Technique On Dynamic And Static Test Of Single Beam

Up to now， because of simple structure and convenient to construct，there is a hugenumber of small or middle measure bridges，in which the reinforced concrete or pre-stressedreinforced concrete bridges have a large proportion. To ensure the construction quality of thesimple beams，we have to detect and survey the bridges and do static test. However， it is awaste of time and money to do the static test. Then， the technology of dynamic test becomesmore and more important.Through the static and dynamic tests of lots of simple beams， we can get the relateddata of the tests. Putting the main concern on the calibration coefficient of strain， deflectionand the ratio of the natural frequency and theoretical frequency， we will get the relationshipof force characteristics of simple beams and them， build empirical relationship of static anddynamic tests. Then，we can evaluate the carrying capacity quickly through the dynamic tests.The paper build the formula by experience through a mass of static and dynamic tests，then create a new and simple test method which can evaluate the loading capacity of thesimple beams.
