| Title of the article | Numerical modeling of some types of standard tests for joints of wooden structures on nail plates |
| Abstract. | Problem statement. Nail plates are widely used in construction as connecting elements for wooden structures. The design of the plates from the 1980s has undergone significant changes in terms of the configuration of the teeth and their dimensions. The test results according to the new standards are not published. Since the study of the nature of the work of joints and structures involves the use of data on the bearing capacity of nail plates, one of the ways to obtain information in this area is numerical modeling. The purpose of this study is to verify models of steel and wood materials as part of a finite element model of wooden structures connected by nail plates through comparing the results of numerical modeling with the results of field tests of metal toothed plates performed by manufacturers and third–party researchers, necessary for subsequent use in calculations of the bearing capacity of joints. As part of the study the following tasks were solved: developing computational models of connections, determining the calculated physical and mechanical characteristics for the model of wood as an orthotropic material and steel as a nonlinear elastic-plastic material, as well as comparing the results of numerical modeling with the results of available data on load-bearing capacity. Results. As a result of numerical modeling, a satisfactory level of correlation of the results with data on field tests of such joints was revealed. Conclusions. The models of materials of 08KP steel and pine wood formulated in the study can be recommended for use in calculations of the bearing capacity of the nail plates using the finite element method. |
