Structural health monitoring (SHM) has gained a significant number of attentions from the engineering communities in the past two decades, which integrates the knowledge of a variety of disciplines including structural engineering, material science, computer science, signal processing, and data management [13]. A main purpose of the development of an SHM system is deemed to facilitate the routine inspection and maintenance activities of the targeted engineering infrastructures. With the aid of an instrumented long-term SHM system, the structural behavior and safety performance of the structure can be promptly evaluated by use of the huge amount of measurement data, and the optimal maintenance schedules can be executed by the infrastructure managers [4]. It includes the connectivity and information exchange between the participating institutions and individual members, the awareness of the SHM and integrity maintenance disciplines and tools among end users, and essential reference materials for the situations where a ranking of structures to be rehabilitated is necessary because of insufficient budget available.

Therefore, in the light of these considerations, this special issue was launched in this journal, an SCI-indexed international journal. The papers in this special issue present the most recent advances, progress, and ideas in the field of the SHM and integrity maintenance and its application. It includes smart, bioinspired, nanometer, wireless, and remote sensing technology, sensor placement and optimization strategies, data compression, cleaning, mining and fusing technology, pattern recognition, feature extraction and damage detection and assessment, design, retrofit, maintenance, renewal and risk management of civil infrastructure, and application of SHM for heritage structures, historical monuments, and old bridges.
