Abstract:
This paper discusses the shaking table test results of three
PP-band (Polypropylene band) retrofitted quarter scale
one-story masonry house models with different roof conditions.
Better connections between masonry wall and roof
connection are one factor to improve the seismic safety of the
masonry houses. Past studies show that PP-band retrofitting
improves the integrity of structural components and prevent
the collapse of masonry structures during an earthquake.
Although the effect of masonry unit type, surface plastering,
the pitch of the PP-band mesh, PP-band connectivity in mesh
and tightness of the mesh attachment to walls were studied by
experiment program, the effect of the roof and its diaphragm
connectivity on PP-band retrofitted masonry structure is nonexistent.
Therefore, an experimental program was designed
and executed for an understanding the effect of the roof and
its connection on the dynamic behavior of the PP-band retrofitted
box-shaped masonry house models. Results reveal that
the PP-band retrofitted models with proper roof diaphragm
improves the seismic behavior with respect to lateral drift,
shear resistance and ductility.
