Abstract: Modern dynamic tests such as networked collaborative pseudo-dynamic testing (PDT) provide new tools to
study the dynamic performance of large and complex structures. In this paper, several networked collaborative PDT systems
established in China and abroad are introduced, including a detailed description of the first networked collaborative platform
that involved the construction of a standardized demonstration procedure for networked collaborative PDT. The example is
a multi-span bridge with RC piers retrofitted by FRP, and a networked structural laboratory (NetSLab) platform is used to
link distributed laboratories located at several universities together. Substructure technology is also used in the testing. The
characteristics, resource sharing and collaborative work of NetSLab are described, and the results illustrate that use of the
NetSLab is feasible for studying the dynamic performance of multi-span bridge structures.
