Summary: This paper proposes an automatic block-by-block pattern generator for multi-leaf nonperiodic masonries, which is then applied in block-based computational analysis of historical masonry structures. The volume of the structure is automatically filled with blocks using the 3D volume of the structure and the 3D block definition of a sample, considering through-thickness blocks and structural details. The efficiency and the generation of statistically-consistent patterns of the filling algorithm are assessed using a meaningful benchmark and applied in full-scale computational analyses.

Summary: The article discusses the technique of structural identification through dynamic in situ tests to understand the impact of Soil Structure Interaction (SSI). Using the bell tower of Santa Sofia in Benevento (Italy) as a case study, the article proposes a noninvasive procedure to collect the necessary data for both structure and soil characterization. The study shows how the dynamic response of the subsoil and the bell tower can be identified and how this information is used to calibrate finite element models for accurate dynamic identification of the built cultural heritage.

Summary: This paper reviews the current state-of-the-art of UAS-borne radars and outlines the future potential of this technology. It categorizes the scientific literature based on application, purpose, technology, and type of UAS. The review shows that there is currently no standard in radar technology, but multi-helicopters are likely to be the most commonly used UAS in the future. UAS-borne radar can be applied in various remote sensing tasks, such as landmine detection, smart agriculture, archeological survey, and search and rescue missions.

Summary: The causes of collapse in masonry buildings differ from those of reinforced concrete and steel-framed buildings due to differences in structural behavior resulting from construction materials and techniques. Out-of-plane behavior of masonry buildings is the most significant contributor to this difference, requiring consideration of both global and local behaviors in evaluating structural performance. This paper presents a seismic performance assessment of a 3-story masonry building using global and local-scale analyses, determining its seismic vulnerability through comparisons with limit values envisaged in local building codes. Local analysis yielded overturning, vertical bending, and lateral bending mechanisms.

Summary: This study investigates the use of the Gamma portable radar interferometer (GPRI) to characterize sea ice displacement and surface topography. The GPRI is found to be best suited for deriving lateral surface deformation and identifying different dynamic regions. The study demonstrates the potential of GPRI in sea ice applications due to its high accuracy in resolving pre- and post-fracture deformation.

Summary: This paper describes an experimental campaign that aims to study the dynamic response of four different helical Wire Rope Isolators (WRIs) loaded along the axial direction. A total of seventy-one tests were conducted with ten cycles of sinusoidal displacement as input to each of them. The dynamic response of the WRIs was analyzed by varying input properties and simulated using a recently developed hysteretic model derived from a new class of uniaxial phenomenological models. The influence of axial preload and wire rope diameter on the dynamic behavior of the tested WRIs is also discussed, and a close agreement between predicted hysteresis loops and experimental ones has been achieved.

Summary: The accuracy of analysis and design of hysteretic mechanical systems can be improved by computing work and energy terms. Nonlinear equilibrium equations and a modified work-energy theorem are derived for MDOF hysteretic mechanical systems. The expressions for path-dependent work and energy change associated with rate-dependent and rate-independent hysteretic forces are derived using the Seleemah and Constantinou (Vaiana and Rosati) model. Nonlinear dynamic analyses are performed to understand the work and energy quantities of the mechanical system's free vibration and forced harmonic vibration responses.
