摘要
随着科技的发展,钢材的高强度和高塑性不能共存的难题得到了成功解决,高强度高塑性钢筋屈服强度达600—900MPa的情况下,伸长率仍能够满足规范要求。新型高强度高塑性钢筋的应用,将对提高人防工程抗力、减小钢材用量、降低施工难度等具有重要意义。本文针对高强度高塑性钢筋应用于人防工程需要首先解决的两个设计计算问题展开研究,为推广新型高强度高塑性钢筋在人防工程中的应用提供理论依据。
With the development of science and technology, the problem that high strength and high plasticity of reinforcement bars can not exist at the same time is solved successfully. The extensibility can meet the code requirements when the yield strength reaches 600 -900 MPa. The application of the new high-strength and high-plasticity concrete reinforcement bars in civil air defence works can increase the bearing capacity of the works, reduce the quantity of concrete reinforcement bars and the difficulty of construction. Two design and calculation problems about the application of high-strength and high-plasticity concrete reinforcement bars in civil air defence works are studied. The study results can provide theoretical bases for the application of the new bars in civil air defence works.
