[0061] The design goal of using the new type of prefabricated concrete structure plastically controllable steel joints in the present invention is: after using the new type of joints, the dynamic characteristics of the structure under frequent earthquakes are approximately unchanged compared with conventional cast-in-place concrete structures, that is, to ensure normal use The stiffness of the structure remains unchanged, and the damper fully functions under fortification intensity or rare earthquakes, absorbing the structural vibration energy input by the earthquake in a concentrated manner, protecting other parts from entering plasticity or restricting the development of plasticity, and the bearing bears the main shear force to ensure that the joints will not collapse. , so as to achieve controllable plasticity and good energy dissipation performance. The node described in the present invention is different from the existing prefabricated concrete structure. It is completely ...
