Time-History Reliability Analysis of Reinforced Concrete Frames under Frequent Earthquakes

By taking earthquake motions as a random process and through time dispersion, a method combining improved pseudo variable method, matrix displacement method and time-history method is proposed to analyze the time-history reliability of reinforced concrete frames that are under frequent earthquakes. This method takes the randomicity of earthquake motions and structural parameters into account, and can be used for reliability analysis of the whole process of an earthquake. An example shows the validity of the method.
