摘要：

A novel explicit method with unconditional stability is presented. This method can be applied to solve general structural dynamic problems. Although its formulation and numerical properties are very similar to the previously published explicit method, it shows much better stability properties when compared the previously published explicit method. These improved stability properties allow its applications to solve a general structural dynamic problem without considering stability problem. It is very computationally efficient since it has the explicitness of each time step and unconditional stability for general structural dynamic problems. Some numerical examples are used to confirm the numerical properties and computational efficiency.
