【正文】 (3)鋼結構的強度、變形及缺陷檢測 鋼結構強度及形變的檢測，常用的有電測法與機測法。材質的單項指標不能代表其全部特征，必須依據常規試驗的各項指標進行綜合評定。如傾儀果測定時拉鋼絲中間遇有障礙。 測試時根據涂層具體情況確定，首先通過儀器確定有無涂層，因在長期環境作用下涂層損傷直至消失涂層，涂層消失與否是涂層的重要參數。超聲波從一種均勻介質傳播到另一種均勻介質時，分界面上會發生聲的反射，從探頭發射的超聲波，經過延遲塊而進入被測件，超聲波到達分界面時，而被反射回來，又通過延遲塊被接收探頭接收，測出發射脈沖到接收脈沖之間的時間，扣除延遲塊時間，根據聲速、時間、距離三者關系，求出被測件的厚度。高強螺栓的質量主要控制項目包括最小荷載檢測、預拉力復驗、扭距檢測、扭距系數復驗及抗滑移系數檢測。 The determination of the scope of the static and dynamic two kinds. Machine is mainly determined the deformation test method (such as deflection, inclination and telescopic deformation identical). In addition, there is surface hardness method, the relationship between the hardness and strength is used to obtain the intensity values. Defect detection on steel structure, the monly used ultrasonic method and electromagic method. To have built steel structure identification, inspection of steel structure material is an important content. Is the most ideal method in the structure of the main stress parts intercepted samples, by tensile test determine the strength of the corresponding indicators. But it will also damage structure, affecting its normal work, and the need for reinforcement. General surface hardness method is used to indirectly infer steel strength. In steel structure buildings, the steel members with welded connections between. Socalled weld nondestructive testing, in order to determine the welding structure or welding parts in forming can satisfy the use requirement, in the case of without widespread destructive test to test the weld technology.
