Abstract
Способ определения диаметра продольной арматуры в упругих железобетонных конструкциях балочного типа, заключающийся в установке их на стенде, закреплении концов по схеме шарнирного опирания, нагружении и измерении физических параметров, с помощью которых по аналитическим зависимостям подсчитывают значение диаметра продольной арматуры конструкции, отличающийся тем, что для конструкций определенного типа изготавливают 6…8 эталонных изделий, диаметр арматуры которых изменяется в определенном диапазоне значений, в каждом из эталонных изделий возбуждают свободные поперечные колебания на основной частоте (или вынужденные колебания на первой резонансной частоте), измеряют эту частоту и по полученным значениям строят аналитическую зависимость «диаметр продольной арматуры - частота колебаний»; при диагностике изделия серийного изготовления определяют его основную (или первую резонансную) частоту колебаний и по полученной аналитической зависимости подсчитывают диаметр продольной арматуры. A method for determining the diameter of longitudinal reinforcement in elastic reinforced concrete structures of the beam type, which consists of installing them on a stand, securing the ends according to the articulated bearing pattern, loading and measuring physical parameters, using which the value of the diameter of the longitudinal reinforcement of the structure is calculated by analytical dependences, characterized in that for structures of a certain type make 6 ... 8 reference products, the diameter of the reinforcement of which varies in a certain range of values, in each of the reference free transverse vibrations at the fundamental frequency (or forced vibrations at the first resonant frequency) are excited by the products, this frequency is measured, and the analytical dependence “longitudinal reinforcement diameter - vibration frequency” is constructed from the obtained values; when diagnosing a serial production product, its main (or first resonant) vibration frequency is determined and the diameter of the longitudinal reinforcement is calculated from the obtained analytical dependence.
