Assembly beam structure experimental model and experimental method

The present invention provides an assembly beam structure experimental model and experimental method. The assembly beam structure experimental model includes assembly beam structures, a worm and gear loading device, a rotation angle restraining and loading device, a supporting and restraining device and a measuring device; the assembly beam structures include two kinds of basic structures, namely, a statically determinate structure or a super-statically determinate structure; rods and nodes are connected together so as to form the statically determinate structure or the super-statically determinate structure; the worm and gear loading device can be manually controlled so as to apply tension and pressure to realize loading and unloading; the magnitude of an applied load can be displayed on a computer through a force sensor; the supporting and restraining device comprises a counter-force frame and restraining supports of the assembly beam structures; and the measuring device comprises the force sensor, a strain
