The digital twin (DT) technique for infrastructures has been developed and attracted a significant amount of attention since 2020. Nonetheless, the key technologies used DT, including load identification (LID), response reconstruction (RRE), damage detection, have much longer history than DT itself. By employing these methods, cyber models are established updated to represent operational state real structure, meanwhile, monitored data at discrete locations can be expanded full-field structure realize DT. In this work, LID RRE methods civil under quasi-static dynamic loading actions comprehensively reviewed. LID, four types formulations derived, solutions summarized address inherent ill-posed problems. RRE, model- data-driven reviewed with five levels performance. Subsequently, several sensing techniques introduced. pros, cons, features highlighted. challenges prospects in outline future trend in-service infrastructure digitalization.
