Experimental Studies of the Deformability of a Frame Tube-Concrete Assembly with a One-Sided Abutment of an I-Beam Cross-Section
Abstract: The article deals with static tests of a frame tube-concrete assembly, in order to study its deformability at one-sided abutment of an I-beam cross-section. The dependence of the angle of rotation of the node on the bending moment applied to it is investigated. The assembly consists of a circular pipe with a diameter of 220 mm with a metal wall thickness of 4 mm, filled with concrete of class B15 and a column fragment length of 1,050 mm. An I-beam steel beam No. 20 with a cantilever span of 1,100 mm is used as a crossbar. The connection of the crossbar to the column is provided by two horizontal and one vertical 5 mm thick plates by welding. The load was transferred to the pipe of the node by the PMM250 press, and to the crossbar by a hydraulic jack with a lifting capacity of 20 tons through the oil station. The force transmitted by the jack was recorded by a compression dynamometer. The step of applying the load to the rack is 20 tons, and to the crossbar - 1.0 tons each. The exposure time of each stage is 3 minutes. The fixation of the rotation angle readings in the plane of the node was provided by PAO-6 deflection meters.
Keywords: frame assembly, deformed state, tubular concrete (t/b) element, hydraulic press, hydraulic jack (GD), experimental model, angle of rotation, bending moment.
