Through the test obtain the hysteretic curve characteristic and skeleton curve of new precast beam-to- column connection.Compared to the cast in place ponent test it could discover that the hysteretic curve of new connection is relatively full but it is a little shrinkage pare to cast in place connection. The ultimate bearing capacity of precast connection was higher than cast in place connection.After a good construction in constructed site the seismic performance of new precast connection could m...
