![]() ![]() As this may not always be possible, it is necessary to consider ways of estimating daily VDVs. ![]() To determine human reaction, VDVs need to be measured for a complete day or night. The paper then considers the analysis of measurements of vibration induced by walking, examining first a range of walking frequencies and then deriving some empirical links between measured peak acceleration and VDV. The relevant guidance given in British Standards is discussed and an example provided to illustrate the analysis procedures. ![]() It defines the parameters used in the assessment of this serviceability issue, including vibration dose values (VDVs) and the frequency weighting that should be applied to vertical vibrations. This paper considers the problem of human acceptance of floor vibrations induced by walking loads. Though it is an ‘industrial building’, the architecture of the CargoLifter hangar is of considerable importance, both functionally and visually, due to its size and impact. The masterplan was developed by architects SIAT Architektur + Technik, Munich, who co-ordinated the planning and were supported at an early stage by a design team, including Arup as structural engineer. #Cargolifter ag berlin plus#The site is a former Soviet airfield in Brand, some 50km south of Berlin, and the whole project comprises the hangar itself, several other buildings for component production, plus a visitors’ centre. No internal structure means less self-weight to lift, so they will be able to carry far more than the approximately 60t of the largest pre-War Zeppelins. For this it has built a hangar in which to produce and maintain the first two of this new generation of CL160 helium-filled airships or ‘blimps’ – so called because they will have no rigid skeleton. The firm CargoLifter AG will use them to lift and transport goods of up to 160t over long distances. What is it like to be a structural engineer?Īfter 50 years airships are once again being developed in Germany. #Cargolifter ag berlin professional#Continuing Professional Development (CPD) ![]()
