For a method of lesser in weight of building structures, we used foamed concrete which consists with light weight aggregates and foaming material of a resin emulsion, and its relative weight is approximately 1.2. We applied the above materials to general reinforced structural member instead of normal concrete. By all means, we proved that the foregoing foamed aggregate concrete is servicable. This is the part of studying report for strength of structural beam which we had experimented at project. The experiment consists of two kinds of test, one is bending and the other is shearing. For bending test, a simply supported beam placed under the repeated load, and cantilever beam connected to a column is under the non repeated load. For shearing test, several kinds of cantilever beams connected to column are used and which are as follow; the one having no reinforced, reinforced with stirrup bars, reinforced with rattice bars and reinforced with both of stirrup and rattice bars. In each cases, uniformely distributed forces are placed on to the farthest point of individual test pieces, which distanced from center of column. As the result of foregoing tests, analysis has made for the crack, stiffness and resistance to ultimated bearing load and etc. to the subjected members. As the conclusion, the test proved that reinforced foamed concrete memder has almost similar behaviour of normal reinforced concrete member, considering the foamed concrete itself has the nature of the lesser weakness in strength, lower in Young's modulus and several factors which are obtained by the experiment.
