钢管混凝土具有诸多优点,使其得到广泛的应用和研究。但也有缺点,如钢材的耐腐蚀性差,导致其后期维护费用较大。由于高强钢可以有效地减小构件的尺寸和结构的重量,不锈钢具有良好的耐腐蚀性能,铝合金具有外表美观、防腐蚀等优点,因此在上述3种金属管中填充混凝土形成新型金属管混凝土结构,具有广泛的应用前景。主要研究了3种金属管混凝土短柱的强度计算公式,并通过有限元模拟验证了公式的正确性。
Concrete has many advantages, making it widely used and studied. But there are also disadvantages, such as poor corrosion resistance of steel, leading to greater maintenance costs later. As the high-strength steel can effectively reduce the size of the components and the weight of the structure, stainless steel has good corrosion resistance, aluminum has the appearance of good, anti-corrosion, etc., so in the above three kinds of metal pipe filled with concrete to form a new type of metal pipe concrete Structure, has a wide range of applications. The formulas for calculating the strength of three kinds of short concrete-filled metal tube columns are mainly studied. The correctness of the formula is verified by finite element analysis.
