The objective of the symposium (YRGS2010) is to provide a forum for young experts from research and practicing engineering communities working in structural engineering and construction to present their latest development，to exchange the information，to discuss the current problems and address the future challenges in structural engineering. This symposium is also aiming to establish a collaborative network for researchers and engineers in structural engineering within Asia-Pacific area.

The present proceedings contain the technical papers that were presented during the 2nd Asia-Pacific Young Researchers and Graduates Symposium that was held in Zhejiang University，P. R. China，27-28 March 2010. We hope you will find the papers in this proceedings interesting and inspiring.
