Abstract
Floors of a building with the relatively new and environmentally sustainable structural material as cross-laminated timber (CLT) and traditional reinforced concrete (RC) are compared in this paper with regard to their load-bearing properties. StruSoft FEM-Design software is utilised to model, analyse and design an existing building using the CLT and RC floors. The building has three stories with a penthouse on the top floor. Modelling, analysis and design of the building can be summarised into five main steps. In step 1, the building with the RC floors is modelled, analysed and designed according to the geometries and specifications of the building. The RC floors of the building are then changed to the CLT floors with the similar thickness and the function of the building is checked for tensile and compressive stresses, utilisation ratio and deflection in step 2. Step 3 involves checking what reinforcing is required for the CLT floors to be approved with about the same thickness as the RC floors. In step 4, it is controlled whether a larger thickness of the CLT floors without reinforcing can withstand the identical conditions of the RC floors. From the obtained results, effects of thickness of the CLT floors and span width are examined. The structural stability of the building with the CLT and RC floors is controlled in step 5. Further, the CLT and RC floors of the building are compared in terms of their stresses, utilisation ratios and weights. The results of this paper demonstrate advantages of using the CLT floors. The CLT floors show good strength properties compared with their low weights. It is uncovered that the building with both of the CLT and RC floors is stable. Obtained results of the building with the CLT and RC floors from the StruSoft FEM-Design software are compared with those from calculations based on Eurocode 2 and Eurocode 5, which reveal good agreements with each other regarding their accuracy.

Comparison is made between the obtained results from the numerical modelling and those from the calculations following Eurocode 2 (EC2) [17] and Eurocode 5 (EC5) [18] for the building having the cross-laminated timber (CLT) and reinforced concrete (RC) floors
Summary
As the population in Sweden increases, high demands are placed on the production of new buildings and in particular housing. The thickness of the boards is mostly between 20-60 mm and the number of layers differs between different manufacturers, but usually 3, 5, 7 or more odd layers of boards are used This is because it is desired to have the highest strength of the material in the main bearing direction, which for wood is along the fibres for both compression and tension. This multi-layered and optimised CLT provides such in-plane and out-of-plane load-bearing capacity that it can be applied as floor panels in the structures [2]. Comparison is made between the obtained results from the numerical modelling and those from the calculations following Eurocode 2 (EC2) [17] and Eurocode 5 (EC5) [18] for the building having the CLT and RC floors
