In　this　paper,　seismic　static　experimental　research　on　short　pier　shear　walls　with　concealed　bracings　without　being　subjected　to　engineering　axial　force　(45°　and　135°　with　engineering　axes)　is　conducted.　By　the　systemic　experiments　on　four　1/2　scale　L-shaped　short　pier　shear　walls　with　concealed　bracings　without　being　subjected　to　engineering　axial　force,　the　main　seismic　performance　indexes　of　L-shaped　short　pier　shear　walls　without　being　subjected　to　engineering　axial　force　are　discussed,　and　the　immanent　seismic　mechanism　is　investigated.　It　shows　that　concealed　bracings　improve　remarkably　the　seismic　performance　of　short　pier　shear　walls　without　being　subjected　to　engineering　axial　force.
