Abstract
The authors have modified the Space Truss Analogy method advocated by M. P. Collins to analyze torsional behavior of reinforced rectangular members. The experimental results are compared with the analytical results from the modified method and with the estimated results from the formulae of ACI Code 318-'89 and -'95. The correlation between analytical results of crack and maximum torsional moments and the experimental results was good. The crack and maximum torsional moments estimated from the ACI Code '95 also coincide with the experimental results. The moments estimated from ACI Code '89 do not coincide with the experimental results. The formulae of ACI Code 318-'95 can be refered to AIJ Standard for structural calculation of reinforced concrete structures.
