摘要

The authors thank Professor Chang for his interest in the KR-α method. However, the authors do not agree with his statement: 'However, two unusual properties were found for KRM and CRM and they might limit their application to solve either linear elastic or nonlinear systems. One is the lack of capability to capture the structural nonlinearity and the other is that it is unable to realistically reflect the dynamic loading.' The authors think that this statement is based on conclusions from using unrealistic numerical examples with unreasonable chosen input parameters (i.e., Δt and ρ_∞) along with unwarranted comparisons as explained subsequently.
