摘      要：Sandwich masonry wall,namely,multi-leaf masonry wall,is widely applied as energy-saving wall since the interlayer between the two outer leaves can act as insulation *** types of sandwich walls keep appearing in research and application,and due to their unique connection patterns,experimental studies should be performed to investigate the mechanical behavior,especially the compressive performance.3 new types of sandwich masonry wall were investigated in this paper,and 3 different technical measures were considered to guarantee the cooperation between the two leaves of the *** on the compression tests of 13 specimens,except for some damage patterns similar with the conventional masonry walls,several new failure patterns are found due to unique connection construction *** were made between the tested compression capacity and the theoretical one which was calculated according to the Chinese Code for Design of Masonry *** results indicate that the contributions of the 3 technical measures are *** modification coefficient(γ)was suggested to evaluate the contribution of the technical measures on the compression capacity,and then a formula was proposed to evaluate the design compression capacity of the new sandwich masonry walls.
