Abstract

The bending behavior of timber beams in a frame systems of modular timber house or permanent timber house needs to be known, specifically for the mechanical properties of bending forces, modulus of rupture, and modulus of elas�ticity. These three parameters are important parameters for the purposes of timber beam design in timber buildings both for non-multistorey and multistorey. One of the experimental testing methods in the laboratory for flexural or bending tests is based on the ASTM D143-21 Standard. The purpose of this study is to do the nonlinear finite element modeling of timber beam and experimental testing in the laboratory that is a flexural test to determine the behavior of beams. The scopes of the research, namely the bending behaviors, reviewed are as follows: the parameters of bending strength, modulus of rupture, and modulus of elasticity, the timber studied is Indone�sian Berua timber, and bending testing is based on the ASTM standard reference which is D143-21. The method that used in this study is based on experimental tests and numerical analyses to obtain the empirical parameter of the bending strength. The results showed that the average flexural strength of timber with experimental test results obtained by 31.52 MPa, modulus of rupture 46.68 MPa, and modulus of elasticity 4143.51 MPa, while the results of the nonlinear finite element modeling showed the bending strength of 29.33 MPa (% difference with experimental results is − 6.96%), modulus of rupture 49.63 MPa (% difference with experimental results is 6.34%), and modulus of elasticity 3477.19 MPa (% difference with experimental results is − 16.09%). These results show that in general the nonlinear finite element modeling produces values that are close to the results of experimental testing. One of the important benefits of numerical modeling is to study the behavior of buildings due to working loads so that predictions of strength, rigidity, and stability behavior can be known. This is important as a reference to the feasibility requirements of the design of a building.
