摘要:
在对文献广泛分析的基础上,应用脉动测试的方法,利用振动反演理论,科学地对现有多层砖房的整体承载能力进行评价,并验证了用反演理论建立的动态参数和砌体平均抗压强度的关系.同时针对完整模态和非完整模态的2种参数识别结果,给出剩余刚度的计算方法.通过对一个1/2缩尺3层砖混房屋模型的动态、静态试验的比较和此方法在工程实例中的运用,成功地验证了采用动态测试方法进行现有多层砖房质量检测、评估的简便性、可行性.
Abstract:
Based on extensive literatures, the bearing capacity of multi-floor brick house is evaluated scientifically by adopting pulsating method and vibration inverse problem theory, and the relation between dynamic parameter and mean strength of bricking-up is verified. At the same time a computational method of residual stiffness is also given aiming at two parameter identification results by the integrated modal and non-integrated modal. By means of experiment on a half-scale model of a three-floor brick house and the applications in practical engineering, the feasibility of this method is proved successfully.
