EXPERIMENTAL STUDY OF LOAD TRANSFER BEHAVIOR OF REINFORCED JOINTS BETWEEN SUPERPOSED SLABS

Publish Date: 2014-05-20

Abstract

Abstract

The paper explored the transmission properties of a new load transfer joint between superposed slabs，static tests of 6 superposed slab specimens with different joint configurations were performed． The whole process from the appearance of cracks to breakage of the slabs was observed，the deflection， shear capacity and plastic hinge were analyzed． The test results showed that the joints performed well which could improve the slabsstiffness and reduce their deflections． The bearing capacity was increased by 13. 3% to 25. 2%; cracks no longer appeared first in the joint． When the maximum cracking width was developed up to 1. 5 mm， there was not plastic hinge． Some proposals for superposed slabsdesign were also put forward．
- superposed slab,
- load transfer joint,
- force transmission property
