In this paper, an example of state-of-the-art monitoring system is presented with its application to the continuous trigger-free dynamic monitoring of the Flavian Amphitheater, widely known as the Colosseum, in Rome, Italy. The installation of the monitoring system, composed of wireless accelerometers located on the top portion of the North façade of the Monument, has allowed to study all the features of recorded vibrations, beyond the usually considered peaks. The system architecture, the wireless protocol and the processing of the data are described in detail in this paper. A discussion on the data collected during a full year of monitoring is presented, with focus on statistical representations of the dynamic response, such as fractiles of the peak accelerations, which are meaningful and synthetic indicators of the effects induced on the Monument by external actions of both natural and man-made nature.

There has been a rapid development in the area of smart structures over the last decade thanks to innovation in sensor/actuator design and fabrication, fiber optics, micro-electro-mechanical sensors (MEMS) and other electronic devices, signal processing and control, and wireless sensors and sensor networks. Structural integration of fiber optic sensing systems represents a new branch of engineering which involves the unique marriage of: fiber optics, optoelectronics and composite material science. Optical fiber sensors have a number of advantages over their electrical counterparts. The transmission of light down an optical fiber is an established technique in optical communications for carrying information and is the primary candidate for resident sensing systems. Fiber optic sensing techniques have been developed as part of aerospace research because of its use in monitoring aeronautical and space structures composed of advanced materials. This technology can be transferred to the field of civil engineering to provide new opportunities in sensing and smart structures.
Design limits are frequently based on strain developing in the structure. Although strain measurement is well established, current practice has until recently been restricted to measurement of point-wise strains by means of vibrating wire (VWSG) or metal foil strain gauges and more recently by fiber optics utilizing Fiber Bragg Grating (FBG) technology. When instrumenting building components such as columns or beams where the strain distribution is merely a function of the end conditions and applied loading, point sensors are suitable to define the complete strain profile. However, where structures interact with soil (e.g. underground infrastructure such as foundations, tunnels or pipelines) or indeed in the case of a soil structure (road or dam embankments), the state of the structure is not fully understood unless the complete in situ strain regime is known. In the context of monitoring strain in underground structures, capturing the continuous strain profile is often invaluable to pinpoint localized problem areas such as joint rotations, deformations and non-uniformly distributed soil-structure interaction loads. In this paper, cases that utilized distributed fiber optic sensing for monitoring the performance of underground structures are presented. The novel aspects of this technology lies in the fact that tens of kilometers of fiber can be sensed at once for continuous distributed strain measurement, providing relatively cheap but highly effective monitoring systems. The system utilizes standard low cost fiber optics and the strain resolution can go down to 2 micro strains. The distributed measurement nature of this technology clearly differentiates from the other discrete point-wise strain measurement technologies. The aim of this paper is to demonstrate the importance of distributed strain measurements to monitor the performance of underground structures. Using the distributed strain data, the performance of underground structures that require rehabilitation, repair and reuse is shown.

A novel structural engineering design approach is described in this paper where flexibility can be added to a masonry shear wall system with the use of a series of steel connector plates that transfer seismic story shear forces to individual masonry wall panels. This innovative form of building construction is termed “hybrid masonry” since structural steel frames resist gravity and lateral forces with engineered structural masonry panels. The steel connector plates are undersized to have considerable flexibility and a relatively low flexural strength. Acting as fuses, these connectors will not only reduce the overall lateral stiffness of a building system, but also dissipate seismic energy through hysteresis. In so doing, the integrity of the structural system to withstand earthquake motions is enhanced. As well, repair costs will be minimized since masonry damage can be circumvented. Replacement of fuse connectors represents a small cost in terms of materials, labor and interruption of building function. Thus, maintenance issues associated with costly seismic repairs can be avoided.
Results of computations will be given that show how lateral flexibility and seismic demand forces can be reduced. A simple two-story, one-bay steel frame with reinforced masonry panels will be used as an example to demonstrate load sharing between the frame and panels when connector strength and stiffness is varied. This test-bed structure has the same configuration as a series of large-scale test structures that were tested at the MUST-SIM facility at the University of Illinois at Urbana-Champaign. Computational models will be calibrated with measured results from large-scale experiments, and then used to examine sensitivities of seismic design parameters to various combinations of connector plate and steel frame stiffnesses.
The paper will highlight the need for adding flexibility to otherwise stiff masonry shear wall structures by making reference to the recent earthquake in Italy (August 2016) where numerous stiff, but weak, masonry buildings were severely damaged. The need to enhance deformation capacity of such structures will be emphasized as well as the overall design objective to reduce the potential for demolition following a destructive earthquake. In general, the paper will promote new innovations in structural design where structural steel and structural masonry are paired to result in a new standard of structural integrity that exceeds the sum of the parts.
