We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb^\ensuremath-1 of data collected at the \ensuremathΥ(4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions B(B+\ensuremath→\ensuremathπ+\ensuremathπ^\ensuremath-\ensuremathπ+)=(10.9\ifmmode±\else\textpm\fi3.3\ifmmode±\else\textpm\fi1.6)\ifmmode×\else\texttimes\fi10^\ensuremath-6, B(B+\ensuremath→K+\ensuremathπ^\ensuremath-\ensuremathπ+)=(59.1\ifmmode±\else\textpm\fi3.8\ifmmode±\else\textpm\fi3.2)\ifmmode×\else\texttimes\fi10^\ensuremath-6, and B(B+\ensuremath→K+K^\ensuremath-K+)=(29.6\ifmmode±\else\textpm\fi2.1\ifmmode±\else\textpm\fi1.6)\ifmmode×\else\texttimes\fi10^\ensuremath-6 and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.
