Technical Insights info@gerb.com Elastic support of JPL power plant turbine in Seoni, India. The site is located near village Barela -Gorakhpur, Tehsil Ghansore of Seoni District. JPL currently has 600 MW thermal capacity fully operational and 660 MW under implementation. The plant is generating power on commercial basis. With a total mass of about 28,750 tons, the turbine house of this power station is approx. 95 m long, 46 m wide and 39-m high. In 2010, GERB was consulted by the operator of the power plant directly and asked for a vibration control solution. We started supporting the owner…

Technical Insights info@gerb.com Building isolation system retrofitted to existing steel columns The architect Daniel Isern, from Isern Associats, with the collaboration of NOLAC Enginyers (Structural Design and Calculation Consultants), AV Enginyers (acoustic consultants) and Albert Bordera (Executive Director of the work) were commissioned to convert the old building of the Catalan Land Institute into a five-star Hotel of the OHLA Boutique Hotels chain, with all its amenities and comfort. Challenge The problem posed by this old office building, for its conversion into a high standing hotel, is that underneath railroad tunnel created vibration immission levels inside, which made it…

https://gerb.com/technical-insights info@gerb.com Upgrade of Elastomeric Bearings to GERB Spring Elements Residential buildings are way more sensitive in case of vibrations because of the individual lifestyle and sentiments of each resident. Whereas a certain level of vibration stress is normal in an industrial environment, this does not apply to residential buildings, where people‘s quality of life is severely affected. Disturbing excitations need to be isolated to protect the living environment. In this case, the vibrations originate from the operation of heat pumps on the roof of a residential building. The initial solution to isolate the vibrations was not successful and…

Technical Insights info@gerb.com One of the world‘s longest driverless rapid transit lines with GERB spring elements in Singapore From Woodlands north to Sungei Bedok, Thomson-East Coast Line (TEL) will serve 32 stations in over 43 kilometers length. When completed in 2022, TEL will be one of the longest driverless rapid transit lines in the world. Construction program already started in 2014 and was carried out by Land Transport Authority Singapore and China Railways First Group. When fully opened, it is expected to serve about 500,000 commuters daily in the initial years, rising to one million commuters daily in the…

GERB Viscous Wall Damper (GVWD) GERB Viscous Wall Damper (GVWD) GERB Viscous Wall Damper (GVWD) Protection of buildings & structures against earthquakes and wind induced vibrations GERB Viscous Wall Dampers (GVWD) are a special design of common Viscodampers®. They are installed in buildings and structures connecting different floors. They are reducing inter-storey drift ratios during wind or seismic excitation. GVWD act in one horizontal direction and increase the overall damping of the structure. Reduced inter-storey drifts result in lower internal forces and moments improving comfort, safety and reliability. Protection of buildings & structures against earthquakes and wind induced vibrations….

https://gerb.com/technical-insights info@gerb.com GERB was approached by a petrochemical company from the middle east region to help mitigate vibration problems from one of their amine plants In total 4 units needed to be solved as vibration level exceeded allowable limits (see Figure 1). The customers internal process study revealed that there is slug flow in the piping which induces internal forces which cannot be eliminated. Considering the limitations like large bore (36”) piping, long vertical runs and the fact that most of the supports are attached to a pressure vessel, it is not feasible to modify the pipe routing or…

https://gerb.com/technical-insights info@gerb.com Providing elasticity at stiffness transition zones between concrete bridge and approach slab Within a comprehensive infrastructure development program, a railway company expanded their single railway network to a double track. The trains run on single, non-electrified tracks with a gauge of 1,000 mm and connects destinations with an expansive rail network of 4,000 km. With the objective to implement a maintenance-free and sustainable upgrade, GERB provided an elasticity solution that reduced all deleterious effects at the transition between concrete bridges and approached slabs. Challenge One remarkable feature of this railway network is the great number of bridges…

Technical Insights info@gerb.com Critical infrastructure, such as hospitals must be protected against earthquakes Slobozia, Romania – 120 km east of Bucharest is the capital of Ialomiţa County. A region that is regularly hit by small to moderate earthquakes. In 2020 alone, the Ialomiţa was affected by 9 earthquakes. Back in 2007, it was clear the hospital, which is providing health care for more than 250,000 people, needed a seismic protection upgrade. Challenge The project challenged on two levels. First, the structure of Slobazia hospital was already built and therefore seismic control solutions were needed to develop that can adapt…
