STRESSEDLY-DEFORMED CONDITION OF JOINT TRUSS TUBE WITHOUT GUSSET PLATE RESEARCH
212 KB
Investigation of the stressedly-deformed condition of the nodes is a key consideration when developing and designing the truss construction. These studies were carried out with the help of numerical and experimental methods considering two variants of the farm nodes without gusset plates design solutions: a model and developed one. Computational investigations were carried out using the software package «Lira 9.6». The above mentioned joints were tested experimentally in specialized units stand made on an individual project. Herewith factors of nodal connections actual work and their limit states have been identified. Also these joints nominal load capacity was defined. The effectiveness of one of the researching solution was detected. It has been established that the engineered solution has a low deformability and high load capacity.
