16錳普通低合金钢钢筋,从1967年起已代替钢与钢筋,在铁路普通钢筋混凝土梁中普遍使用。由原铁路专业设计院编制了16錳普通钢筋混凝土梁(跨度为2.4m～20.0m)设计图,图号为专桥〈1013〉、〈1014〉、〈1015〉、〈1016〉。设计中未考虑到焊接疲劳强度的影响,16錳钢筋的容许应力采用1800kg/cm~2,并由原专业设计院与铁道科学研究院共同进行了针对钢筋母材的六片模拟小梁的靜力和疲劳试验。试验表明可以符合设计要求。 1968年经原铁道部再决定,仍由专业设计
16 Manganese ordinary low alloy steel rebar, steel and steel has been replaced since 1967, commonly used in ordinary railway reinforced concrete beams. The 16Mn ordinary reinforced concrete beams (span of 2.4m ~ 20.0m) are designed by the former Design Institute of Railway Engineering, with the figure numbers of <1013>, <1014>, <1015> and <1016>. In the design, the influence of welding fatigue strength is not taken into consideration. The allowable stress of 16 manganese steel bars is 1800kg / cm ~ 2. The original professional design institute and the Academy of Railway Science jointly carried out the simulation of six simulated trabecular bars Force and fatigue test. Test shows that it can meet the design requirements. In 1968, it was decided by the Ministry of Railways that it was still professionally designed
