-
摘要: 碳纤维材料近年来被广泛用于结构的修复、加固领域，用于柱的抗震加固，可以有效约束混凝土的变形，从而使其承载能力及延性能力有很大提高；给出了碳纤维片材的折算体积配箍率的统一计算公式；基于相关设计规范，对柱碳纤维抗震加固的计算理论进行了探讨，并设计了计算流程，应用VB语言编制了软件；最后，介绍了东大迪普加固软件系统的柱碳纤维抗震加固设计界面与计算方法，并应用实例进行了详细说明Abstract: In recent years CFRP is widely applied to the field of rehabilitation and retrofit of existing structure, which can effectively confine the deformation of the concrete so that the carrying capacity and ductility capability of the structure are increased remarkably.The uniform calculation formula of the conversion volume stirrup rate of CFRP is given.Based on the relevant design specifications.The basic calculation method of seismic strengthening for reinforced concrete columns is introduced, and calculation flow chart of seismic strengthening is designed and software design by Visual Basic is also realized.CFRP seismic strengthening design interface and calculation method of columns of Southeast University Deep Strengthening Soft System(SEU_DEEP) are introduced and one practical example is presented to illuminate in detail.
