| Abstract: | In the world of construction foundations are a core element of structural engineering. As today’s society strives to optimal sustainability developments are made every possibility that occurs. A big missed opportunity in the construction field is in the material use in underwater concrete floors. Underwater foundations are held by anchors. These foundations initially experience a lot of upward force due to waterpressure and later experience a lot of downward forces due to loads of the structure. Therefore the anchors need to be resilient against both tensile and compressive forces. To be strong enough, sufficient spacing between the anchor and the flooredge should be applied. Consequently these floors become very thick and use up loads of concrete. This problem can easily be solved by implementing a double anchorage. This research paper looks into the effects of double anchor plates on GEWI-piles on punching shear. GEWI-piles are used for foundation of among others underwater concrete floors. The paper answers how double anchors improve the punching capacity at different floor thicknesses and/or how much the thickness of the floor can be reduced while remaining equal/similar punching capacity. The punching capacity is tested on the stress over the area around the anchors. The model used in this research is based on a segment of a bus underpass that is currently being built in Groningen. The results concluded that a double anchor at equal floor thickness experiences about half the stress levels. When remaining similar punching capacity, the thickness of an underwater concrete floor can be reduced by 20% percent by using a double anchor rather than a single anchor. |
