Reviewer 3 Report

This paper studied a comprehensive method based on second-order direct analysis method has been applied for optimization design of long-span steel transfer truss in the Redevelopment of Hong Kong Kwong Wah Hospital (KWH) – Phase 1. The numerical and theoretical investigations were conducted. However, there are still some questions, which need to be answered before the publication.

1, what is the material model used in numerical analysis? The linear model or the nonlinear model? More details on this issue should be added.

2, the differences in vertical displacements between the original and optimal designs are not very clear. More discussions are required.

3, Fig. 9. What is the longitudinal coordinates?

4, Section 4.6. is it possible to give the data and figure to clarify the time saving？

5, Section 3.4. The applicable of the simple weld connection should be proved, rather than weld and bolt.
