The invention discloses a portable performance test device for
automatic control of a combined action of a bidirectional load of a beam-column joint and a determination method. The test device comprises an outer frame fixing device, a test piece fixing device, a test piece loading device and a
data acquisition system, wherein the outer frame fixing device comprises a trapezoidal horizontal counter-force frame, an I-shaped girder bearing platform, an I-
shaped beam, an I-shaped upright and a prestress
wire rope; the test piece loading device comprises a horizontal
actuator, two vertical actuators, a hydraulic oil source, a horizontal load sensor and a
vertical load sensor; the test piece fixing device comprises two steel splints, an
anchor bolt rod, a column fixing base and a column bottom hinge support; and the
data acquisition system comprises a controller, a multi-channel strain collector and a computer. The device, provided by the invention, has the advantages of simple structure, convenience for
assembly and disassembly, and few required materials, and is suitable for testing hysteretic behavior of a node test piece at scientific research and construction sites.
