Numerical Analysis on Global Serviceability Behaviours of Tall CLT Buildings to the Eurocodes and UK National Annexes

Cross-laminated timber (CLT) is an innovative engineered product and has been widely used for constructing tall buildings due to its excellent structural performance good strength with multi-layers of boards in both perpendicular directions. However, the global serviceability constructed from CLT products lift core, walls, floors under wind load not well known yet, even though it crucial a design. In this study, finite element software SAP2000 numerically simulate static dynamic behaviours 30-storey building assumed Glasgow, Scotland, UK. The maximum horizontal storey displacement only 16.6% design limit 13.8% set Eurocodes. first three lowest vibrational frequencies, modes shapes were obtained, fundamental frequency being 19.9% larger than code-recommended value. Accordingly, peak acceleration was determined as per Eurocodes ISO standard. results show that satisfy requirements other standards. Parametric studies on accelerations also conducted by varying material properties masses. By increasing grade members, generalised mass stiffness can all be adopted lower at top level building, so reduce human perceptions wind-induced vibrations respect acceleration.
