Dr. Rosario Montuori, Professor

Dr. Rosario Montuori, Professor

Department of Engineering, University of Salerno, Salerno, Italy

Biography:  Dr. Rosario Montuori is full Professor of Structural Engineering at the University of Salerno, Italy. He received a M.S/B.S. in Civil Engineering from the University of Salerno in 1997 and the PhD in Structural Engineering from the same University in 2001. He is author of more than 150 journal articles, conference papers and scientific reports. His principal research activity is devoted to the control of the collapse mechanism for steel structures by means of a rigorous application of “capacity design”. In particular, the research activity concerns the following structural typologies: Concrete Moment Resisting Frames, Steel Moment Resisting Frames with semi-rigid joints, Steel Irregular Moment Resisting Frames, Concentrically “X” and “V” Braced Frames, Concentrically “X” Braced Frames with Reduced Section (based on the reduction of the cross section area at the ends of the bracing members aiming to calibrate the axial resistance to a value equal to the internal action occurring under seismic load combination), Eccentrically Braced Frames, Moment Resisting Frame-Concentrically Braced Frame dual systems and Truss Moment Frames with special devices located at the bottom chord level at the ends of the truss girders. For several of the considered structural typologies, also the seismic structural reliability defined as the mean annual frequency (MAF) of exceeding a threshold level of damage, i.e. a limit state has been investigated and compared with reference both to the proposed design methodologies and to EC8 provisions. He developed theoretical fiber models able to predict the Moment-curvature behaviour of RC columns confined by means of angles and battens and of Concrete Filled Steel Tubular Columns (CFT) with Square Hollow Section (SHS). The proposed models have been validated by means of experimental tests. He developed a design procedure for some Tensegrity Structures able to account both for local and global stability in order to find the optimal design of minimum mass. He has participated as research staff member in various research projects funded by the Italian Ministry of Education and the Italian Network of Seismic Engineering Laboratories (ReLUIS).

Topic: Rational Seismic Design of Steel Moment Resisting Frames Equipped with Dissipative Devices

Abstract: The design of steel structures equipped with energy dissipation devices requires a fractional approach to ensure optimal performance during seismic events. In the event of an earthquake, the dissipative devices integrated within the structure must activate precisely, with all and only the designated dissipators engaging in plastic excursions. Meanwhile, the remaining portion of the structure must remain within the elastic range, ensuring that all non-dissipative members remain undamaged. This approach to design aligns perfectly with the principles of capacity design, which are fundamental for ensuring structural resilience under seismic loading conditions. However, many modern design codes only address these criteria from a partial rather than a global perspective. This presentation will explore the importance of adopting a fractional design approach to effectively integrate energy dissipation devices into steel structures while maintaining overall structural integrity and seismic performance. Additionally, the keynote will provide a clear overview of simple and rational design procedures capable of activating only the designated dissipative zones during collapse. These procedures ensure that energy dissipation devices integrated into the structure engage precisely as intended, effectively dissipating seismic energy input. Several simple examples will be shown and discussed.

Topic: Research and Application of Buckling Restrained Steel Plate Shear Walls

Abstract: In this study, a novel type of coupled steel tubes is proposed and utilized as buckling restraining members in BRSPSWs. These coupled steel tubes offer advantages of lightweight construction and ease of assembly. The transition from partial to full constraint of the steel plate can be achieved by adjusting the number of coupled steel tubes. Quasi-static cyclic loading tests are conducted on specimens including unstiffened, partially buckling restrained, and fully buckling restrained SPSWs. The in-plane mechanical properties and out-of-plane interaction behavior are obtained. simplified models of BRSPSW are established to analyze interaction behavior between steel plate and buckling restraining members. The working mechanism is clarified and formulas that unify the calculation of out-of-plane interaction force for both the fully and partially BRSPSWs are proposed. Finite element models are established and validated using the test results. Parametrical studies are conducted to investigated the effect of key parameters on the in-plane and out-of-plane performance of BRSPSW. Finally, the experiment and FE results are applied to validate the accuracy of the proposed formulas. Necessary modification factors are derived and simplified design method of the out-of-plane buckling restraining members is proposed.
