CONSTRUCTION METHOD FOR HIGH-DUCTILITY MASONRY WALL HAVING REINFORCED JOINT MORTAR LAYER

摘要

A construction method for a high-ductility masonry wall having a reinforced joint mortar layer, comprising the following steps: 1. wetting in advance building blocks used for building a wall; 2. applying, according to the size of the cross section of the wall, high-performance joint mortar having a thickness of 3-5 mm to a first building block along the cross section of the wall; 3. laying a geogrid mesh or a steel wire mesh on the high-performance joint mortar, applying high-performance joint mortar having a thickness of 3-5 mm to the geogrid mesh or the steel wire mesh, and laying a second building block on the high-performance joint mortar layer; and 4. repeating steps 2 and 3 to complete wall building according to the design height of the masonry wall. The construction method can improve the stress performance of the entire masonry wall, enhance the ductility and integrity of the masonry wall, obstruct transfer paths of shear cracks, and improve the shear performance of the masonry wall, thus improving the seismic performance.
