24 Oct Bolina Ingegneria
Soil Energy & IT has agreement to set up Joint Venture company and aim to involve together with improvement of construction industry in Myanmar. Bolina Consulting Office is mainly working design and construction of complex projects, covering the early phases of conceptual design and definition of specification up to implementation, optimization and validation. The company is continuously supported by the most advanced technical technical and scientific development, where research pay a relevant role. Some of Bolina Portfolios are THE “GRANATIERI DI SARDEGNA” BRIDGE IN THE OUTSKIRTS OF VENICE, ITALY, 2006 The bridge is characterized by a five 100 m composite steel and concrete arched structure over a total length of 500 meter. The cross section has a total width of 17,86 m. BOLINA Ingegneria Ltd.was responsible for the seismic design and structure. The fundamental idea leading the optimization process was to remove the maximum amount of un piloted material from the lower stressed zones with the objective to find the final optimal solution, corresponding to the lightest possible one. This bought to a weight reduction in the superstructure of 70% compared to a corresponding layout for a pre stressed concrete layout and to the realization of a new shape of the deck where elliptical holes were located at the bottom of the steel structure of the main bays. LIFT-UP SYSTEM – BUILDING IN 87 TURATI STREET, 2011, AQUILA ITALY, 2011.
The existing building has a concrete rectangular frame with columns and beams (24,00×10,80 m) and six levels. The damages suffered during the 2009 earthquake cause main structural collapses “E group” classified. A geometric survey and an experimental testing were performed to determine the characteristics of the building materials. The design study was to compare the usual ways for the refurbishment and seismic retrofitting about the existing buildings: (a) reinforcement of the section of the structural elements and the increase of the ductility; (b) putting bracing elements; (c) seismic retrofitting by isolation bearings on the columns. At the end of this studies the seismic retrofitting was chosen because didn’t need reinforcement elements for the erection phase even some complexity in the realization.
