Typical Scenario

A building context as complex as that of many historical centers in Europe is the typical scenario where more and more technicians found themselves at work. In addition to the usual difficulty of dealing with the complexity of masonry building clusters, they particularly feel the lack of the essential support of dedicated computational tools. In fact, the calculation codes currently available do not address modeling and analysis of building clusters in a personalized manner. VENUS, Italian acronym for Nonlinear Assessment of Structural Units, is a software developed in C++, which deals with the seismic assessment of building clusters in an integrated manner, accompanying the practitioner from the early stages of defining the level of knowledge, to the management of the design quantities, until the graphic elaboration of the results. Finally, it allows to test the effectiveness of a local intervention with traditional and innovative strengthening techniques and to evaluate its effects on the global response. Finally, a brief description of a stochastic approach foreseen in a future version of the software is discussed.

The Ideal

In seismic areas, masonry construction is prone to brittle failures due to the mechanical behavior of the constituent materials and to the low capacity of force redistributions. The redistribution capacity is mainly due to the presence of horizontal connections upon the walls and to the stiffness of the roof, which is typically a vaulted structure. The modeling of the global behavior of a masonry building, taking into account the accurate stiffness of the vaults, is a major issue in seismic design and assessment. The complex geometry of the vaults can be considered as an equivalent plate, able to replicate the stiffness behavior and the force redistribution capacity of the real vault. In this study, the efforts of the authors are addressed to the definition of a plate, able to replace the vaulted surfaces in a global numerical model. The ideal diaphragm is considered as a generally orthotropic plate with the same footprint and the same thickness of the original vault. An extended parametric study was conducted in which the mechanical and geometrical parameters were varied, such as the vault thickness, its dimensions, the constraint conditions, and the possible presence of side walls. The results are presented and discussed herein, with the aim of providing useful information to the researchers and practitioners involved in seismic analyses of historical masonry construction.

Historic buildings and monuments are an important part of our cultural heritage that must be protected and their sustainability ensured, especially when earthquakes occur. In this paper, a technique that uses structural steel frames is proposed as one way of strengthening unreinforced masonry (URM) in historical buildings. The idea underpinning this technique is to reduce the earthquake displacement demand on non-ductile URM walls by attaching steel frames to the building floors from inside. These frames run parallel to the structural system of the building and are fixed at their base to the existing foundation of the building. Furthermore, they are constructed rapidly, do not occupy architectural space, save the building’s historic fabric, and can be easily replaced after an earthquake if some minor damage ensues. The proposed technique was applied to a five-story historical masonry building in Istanbul. The results of seismic performance analysis indicate that even though the building has plan irregularities, the proposed steel frames are able to effectively enhance the building’s seismic performance by reducing inter-story drifts and increasing lateral stiffness and strength.
