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(-1) of data collected at the Y(4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions <B(B+&RARR;π(+)π(-)π(+))=(10.9&PLUSMN;3.3&PLUSMN;1.6)x10(-6), B(B+&RARR;K+π(-)π(+))=(59.1&PLUSMN;3.8&PLUSMN;3.2)x10(-6), and B(B+&RARR;K+K-K+)=(29.6&PLUSMN;2.1&PLUSMN;1.6)x10(-6) and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.
