Abstract

The joist is one of the critical element in timber floor system affecting floor performance, especially deflection. Types of timber used in floor joist as well as its dimension decide the length of floor span. The floor span length increases with the higher strength and resistance to shear and bending stress, as an example, if using engineering wood product such as glulam has the superior material properties than softwood and hardwood so the strength limitation of floor increases accordingly. In order to ensure the good performance of floor with obeying to building code, each country have their code of practice respectively to follow when doing flexible timber structure design. Nowadays, in Malaysia, Eurocode which pursues limit state design is used as the mandatory standard since British Standard is no longer used, and the Eurocode 5 (EN1955-1-1) is applied for timber structure design. In a short word, ultimate and serviceability limit state are necessary checked to prevent failure and instability of timber floor and to decrease the discomfort of occupants. Nonetheless, the process to design floor joist requires extensive data and formulae, and undoubtedly the time taken for this design calculation will be long. Therefore to shorten time taken and to make design process more effectively, a spreadsheet using Microsoft Excel for timber floor joist design is developed in this study to serve purpose of assisting designer or engineer to perform easier. A case study is conducted at Pasir Gudang Café to find the optimum joist dimension with optimum joist spacing and floor span after check the ULS and SLS requirements. Vibration performance of flooring is highlighted in this study.
