Cavity walls structure is unsuitable in cold area for its faultiness of poor heat-insulating property. But the cavity walls constraint masonry construction is suitable in cold area for its high heat-insulating property. Studies are carried as setting up the restoring force model of the cavity walls confined masonry structure and analyzing the dynamic time-history of cavity walls constraint masonry structure under 7 degrees small earthquake, middle earthquake or large earthquake through EL centro wave, TALF wave, Ninghe wave and Qian'an wave, which indicates that cavity walls constraint masonry construction can satisfy seismic demand of 7 degree quake. Finally, the formula for calculating the interlayer displacement of cavity walls confined masonry structure near collapse is put forward and the counting result is compared with that of dynamic time-history analyzing, which shows that the accuracy of this formula is high enough to be used for analyzing the seismic performance of cavity walls constraint masonry structure.

The interface between the head of the window and the wall represents one of the largest thermal bridges of a building and one of the areas with the highest risk of surface condensation. Additionally, it studied the reliability and accuracy of assessing this thermal bridge using an adiabatic surface instead the actual window.
