چکیده مقاله
This study presents strut and tie models STM explaining the development of bond strength along bonded length together with anchorage by head bearing of headed bars The anchorage at a head requires construction of a biaxial compressed nodal zone and bond resistance needs to use the concept of a smeared node This model consists of a strut with the nodal zone at head for head bearing and fan shaped stress field for bond stresses along the development length This modeling clarifies interaction between head bearing and bond resistances where a bond transfers along the development length of headed bars is necessary for a smooth force flow The experimental results For series of headed bars with relatively small area of plate heads are interpreted 1 by this proposed model
