The thesis presents static analysis of timber roof structure of Academy of Fine Arts and Design cultural
heritage building at Erjavčeva St. in Ljubljana. In the first part of the thesis, the measurement process and overview of existing documentation is described. Due to inaccessibility and prohibition of structure modifying, at many parts of the structure the basis for drawing an architectural plan of existing situation were old plans and old instructions for building timber roofs. Afterwards, 3D architectural model of roof structure was made. It was the basis for computational model, which was determined by taking Eurocode standards and manual for the design of building structures to Eurocode standards into account. Such as an architectural model, the computational models for every structure element, which carried out controls in limit states are also shown. Static analysis was carried out in SAP2000 software. Based on calculated internal forces, displacements and basic terms for limit states controls, given by standard SIST EN 1995- 1-1:2005, structure element controls were carried out for ultimate limit states and serviceability limit states. In the last part of the thesis results are summarized. In ultimate limit states most of the structure elements are safe, while in ultimate serviceability limit states most of the structure elements are useless.
