| Summary: | There are reported roof failure due to uplifting of the roof structures or roof sheeting during rainstorm has been causing damages to the buildings. Generally, failure occurred at the two points, either at the roof truss’s sheeting or at the truss to roof beam connections. There are 2 types of structure are to be analyzed; the different of these two building will be the buildings dimension, meaning that one is a single storey houses and other is a 20 storey apartment. The roof structure’s data is extracted from the reported cases for simulation purposes. For a more conservative result, the wind speed is taken as 40 m/s. Due to different aspect for this 2 type of structure, the wind-uplifting force will be determined. The calculated resulting forces transferred at different connection points were compared with the experimental result obtained from laboratory testing. The result of this, is that the connection of both houses and apartment is safe under the wind speed of 40m/s. However, this happen when the proper used of selected material plus all the material is in well condition. To improve the study of this project, the larger scale testing like wind tunnel can provide the more accurate result due to the integrity of the roof structure. |
