Experimental study on impact resistance of fabricated masonry wall
Prefabricated masonry wall panels are susceptible to human or construction machinery impacts during transportation,installation,and use,which may cause significant deformation or damage.To study the impact resistance performance of prefabricated masonry wall panels during transportation,installation,and use,the pendulum method was used to conduct impact tests on prefabricated automatic stacking masonry wall panels with only horizontal mortar joints and traditional manual masonry wall panels.The displacement characteristics,cracking conditions,and failure forms of the wall panels under external impact loads were tested and analyzed.The experimental results show that the horizontal and vertical displacement of prefabricated masonry wall panels with only horizontal mortar joints is greater than that of wall panels built using traditional stacking techniques;When the wall panel is impacted,the overall stability of the wall without vertical mortar joint constraints decreases,and the impact load outside the structural plane has a significant impact on the wall.After 10 impacts,cracks appeared on two sets of walls,which developed from top to bottom;After 15 impacts,structural damage occurred,but the impact resistance performance of the wall panel meets the requirements of the specifications,which can meet the actual engineering needs.
