From the point of view of type divides in detail, including brick setting, block masonry, barnacle body, wallboard masonry etc., these masonries by clay brick, building block,
The blocks such as stone material are built by laying bricks or stones with mortar, have the characteristics that easy for construction, low cost, fire resistance and endurance quality are good, in China
It is widely used.Masonry structure also has following defect simultaneously：
First, intensity is relatively low, more from great and dosage；
Second, quality is built by laying bricks or stones horizontal different and can not be ensured by construction personnel；
Third, shock resistance and tension, shearing strength are all relatively poor, and the anti-bending strength of masonry is also relatively poor,
Therefore anti-pressure ability cannot fully play；
4th, the cohesive force between mortar and bulk is weaker, resist masonry straight joint normal tension (straight up) and tangentially
The ability of power (horizontal direction) is poor.
Simultaneously again due to the gravity of masonry structure itself, masonry straight joint does not have normal tension generally；But China belongs to
In earthquake prone areas, under the action of earthquake load, the tangential force of masonry straight joint is often larger.Masonry resists straight joint tangential force
Ability, be determined by the tangential adhesion strength of area and straight joint of masonry straight joint, thus masonry straight joint tangentially bond it is strong
