Seismic behavior of perforated brick walls with HPFL strips composite ring beam and constructional column

Abstract

The existing perforated brick masonry structures are usually lack of ring beam and constructional column. Aiming at this problem, a new method of HPFL strips composite ring beam and constructional column is proposed. Six perforated brick walls with HPFL strips composite ring beam and constructional column and two comparative walls are tested under low cycle reversed loading. The failure mode, ultimate strength, energy dissipation capacity, and ductility of the strengthened walls and the comparative walls are compared. A calculation method is proposed for predicting the seismic shear capacity of perforated brick walls with HPFL strips composite ring beam and constructional column. The results show that using this method, the cracking load, ultimate load, energy dissipation capacity and deformation capacity are improved greatly. The calculated results are in good agreement with the measured results. The calculated method can provide the reference for seismic strengthening design of the perforated brick masonry.
