钢筋混凝土外粘钢板结构裂缝的有限元数值模拟

随着高技术武器的不断发展,防护工程正面临着前所未有的威胁和挑战,新型防护结构及材料已经成为研究的热点。针对这一实际背景,运用ANSYS大型有限元软件,采用数值模拟的方法对普通钢筋混凝土结构和外粘钢板混凝土结构在相同均布面荷载作用下的变形、钢筋应力以及结构裂缝的开展情况进行了比较。结果表明外粘钢板的钢筋混凝土结构能够大大增强结构的抗力,并且有效的抑制了裂缝的开展。

Finite Element Analysis on Cracking in Reinforced Concrete Structure Bonding A Steel Plate

With the development of high - tech weapon, the defense engineering is being faced with the menace and challenge that are not in existence before. New - style defense structures and materials have become the hotspot in the field of defense study. In view of the issue above, finite element analysis is used to simulate the phenomena of reinforced concrete structure and reinforced concrete structure with steel plate by the uniformly distributed load on the surface . The comparison includes displacement, the stress of the steel bar and crack . The results show that bonding steel on the bottom of structure can enhance structures capacity very much and hold back cracking in the structure effectively.
