Shanghai Expo Puxi Entertainment Hall is reconstructed based on existing workshop building. To meet new function requirements of the hall, a structural column is removed and replaced with a jacking beam. A structural safety monitoring system is proposed and applied to evaluate the real-time structural state and ensure the structural safety. Vibrating wire sensors and FBG sensors are installed to monitor the stress of member of the space truss structure; ForesightTM series DSTS (Distributed Strain and Temperature Sensors) is installed to monitor the stress of the jacking beam. Results show that the structural safety monitoring system works stably. The safety monitoring system reflects the real-time behavior of the structure and controls the structural reconstruction safety effectively.

The technology monitoring the operating state of the architecture construction is always hot topics in civil engineering. In this paper, attempts using the NiTiSMA film/ferroelectric ceramics PZT composite materials with the function of force - electricity conversion are introduced to the design of structural safety monitoring system. The sensing materials based on the function of force - electricity conversion, directly perceive the stress changes of architectural structure under the vibration loads, monitoring the state changes of internal cracks in the architectural structure. The results show that the safety monitoring system of architectural beam structure,on the sense of NiTiSMA film / ferroelectric ceramics PZT composite materials, possesses reaction speed in milliseconds, response frequency at 0-1000 Hz. It is suitable for monitoring the damage status of cracks in the architecture construction.

The structure of the power tunnel is unique as a special place. It is built under the surface of the earth crust,belongs to half-hidden project. In recent years, affected by operating life, geological conditions, design and construction, the number of the tunnels which has structural safety risks apears more and more, so the safety of the tunnel structure always has been a very important issue of construction, operation and maintenance. This paper presents a tunnel structure safety monitoring system based on BOTDA technology.This system has good adaptability to the scene, and can remotely monitor the structural safety of the tunnel in real time, and it also has advantages of distribution, long-distance, high-precision, etc.

The effective construction of safety monitoring system at construction site depends on perfect management system and advanced technical support. And the lack of information technology platform, resulting in reduced management efficiency, information is not accurate and other issues. Based on the construction site safety monitoring system to achieve the goal, to do a good job in advance prevention, to take the latest information collection technology RFID and BIM integrated comprehensive and effective monitoring of the construction site, constitute the main technology in the monitoring system, thus ensuring the construction site safety monitoring efficiency , Comprehensive, real-time, etc., on the management and technical two points to achieve the construction site safety monitoring, improve the quality of safety management.
