    Abstract

    Demand for wood as a construction material generally met from logging with good quality and old enough, so the timber that has good quality is decreasing because the timber growth rate is not comparable to the speed of timber harvesting and wood utilization. One alternative to solve the problem is using the Laminated Veneer Lumber (LVL) of sengon. Sengon timber has short harvest period is about 5-10 years so it can be guaranteed for the availability. Wooden building structures loaded for extended periods will decrease due to creep effect. Creep represents an deflection that occurs in a structural component that is affected by time. Therefore, it is necessary to study with attention to effect of the long time loading to the strength of the wood. The aims of this study is to determine the behavior of creep and the creep factor value of LVL Sengon. The test results is the creep factor value that can be used to predict the deflection for a longer time span. This research was carried out using test specimens as many as 54 pieces of wood sengon LVL beams consists of 6 different cross-sectional dimensions and 3 types of loading. The testing of creep was carried out by burdening the middle span for 7 days indoors. The study results is creep factor value that can be used to design buildings with construction materials Sengon. This research can estimate the structure used is safe or not when burdened during the life planning. From the results of the creep factor is concluded that the planned timber structure, should take into account the flexural strength and deflection which occur during loading. Including the type of timber to be used for the construction of the structure due to the behavior of the structure of each timber is different. Keywords: creep, MOR (Modulus of Rupture), Laminated Veneer Lumber
