Upgrade of Elastomeric Bearings to GERB Spring Elements Residential buildings are way more sesnitive 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…

One of the world‘s longest driverless rapid transit lines with GERB spring elements in Singapore From Woodlands north to Sungei Bedok, Thomson-East CoastLine (TEL) will serve 32 stations in over 43 kilometers length. Whencompleted in 2022, TEL will be one of the longest driverless rapidtransit lines in the world. Construction program already started in2014 and was carried out by Land Transport Authority Singaporeand China Railways First Group. When fully opened, it is expected toserve about 500,000 commuters daily in the initial years, rising to one million commuters daily in the long term. A GERB Floating Slab Track system…

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….

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 existing…

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 and…

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 to already…

Protecting teaching experimental equipment from vibration and structure-borne noise The extension of Peking University was completed at the end of August 2021 with a new teaching and office building providing more space for students and staff. GERB has already supported the project in 2018 with engineering and delivering an elastic support solution to protect members and structures from unwanted vibrations. Challenge A subway line running underground threatened the new structure with negative effects of vibration that could cause affect the normal use of the teaching equipment as well as a significant reduction of comfort for people in the…

GERB‘s first building project on spring elements in India is currently being implemented in Mumbai City,Maharashtra. In 2018 Shrem got in touch with GERB by introducing their architect and consultant new designed Fairmont hotel. As Shrem is a developer in hospitality real estate and infrastructure, the requirements in this project focus on high customer comfort and safety standards. Due to increased threats from vibrations in the metropolitan area, the structure demanded a GERB vibration isolation solution. With our mission to increase comfort and protect against vibrations, structure-borne noise and earthquake, the client could rely on our full support….
