CONTACT JOINT STRENGTH OF PRECAST COLUMNS WITH DEFORMABLE CENTRING LAYING
Due to growth of number of storeys in a dwelling and public buildings for mass gatherings (up to 20-25 storeys) requirements of their construction industrialization necessitate designs of precast column joints which are capable to bear high loads (up to 10-12 МН and more). The paper presents an anal...

| description | Due to growth of number of storeys in a dwelling and public buildings for mass gatherings (up to 20-25 storeys) requirements of their construction industrialization necessitate designs of precast column joints which are capable to bear high loads (up to 10-12 МН and more). The paper presents an analysis of the known contact joint designs used in the columns of frame buildings and the analysis shows that the these design are rather efficient. However these joints are sensitive to accuracy of column butt end fabrication. Bearing capacity of joints can be significantly decreased in case of comparatively small ends out of square. It has been decided to introduce a deformable centering laying made of soft steel in a joint design in order to exclude the mentioned disadvantage. Due to its plastic deformation the laying ensures transformation of longitudinal effort occurring in it to the column axis. As a result of it we obtain the most advantageous position for joint design required for transfer of compressing force at column longitudinal axis.Experimental investigations of contact joints with a deformable centering laying have been carried with due account of the requirements to construction standards, results of the executed works and main results of the investigations are presented in the paper. Proposals for calculation and designing of these joints have been given on the basis of the obtained data and works. It has been shown that application of the centering laying with corresponding concrete confinement reinforcement at the joint make it possible to ensure the required bearing capacity and reliability. |
