摘要： PROBLEM TO BE SOLVED: To provide a technique of analyzing a structure inclusive of a concrete structural element, like an exposed column base, in an elasto-plastic region, by using a cross sectional analysis.
SOLUTION: There is provided a structure analyzing method which includes a step of calculating estimated deformation volumes of a concrete foundation, an anchor bolt, and a base plate, respectively, for instance, by using the cross sectional analysis, and a step of calculating a relationship between an estimated moment value and a rotational angle in the elasto-plastic region of a connection portion, based on the respectively calculated estimated deformation volumes. In the step of calculating the estimated deformation volume of the concrete foundation, a truncated cone is set by expanding a cross sectional area from a working surface to which a compressed load is applied, at a predetermined inclination angle as a depth becomes deeper, as an effective region in which the deformation occurs due to the compressed load, and a distortion at each horizontal cross section of the truncated cone is calculated from a balance of force on the cross section. Then the calculated distortion is integrated to calculate the estimated deformation volume, and the inclination angle is set such that the deformation volume calculated from an equation of elastic theory is equivalent to the estimated deformation volume in an elastic region.

摘要： PROBLEM TO BE SOLVED: To provide the joining structure of an RC beam and an S beam in which time for construction is reduced, and the RC beam and the S beam can be joined with high accuracy.
SOLUTION: Vertical stiffeners 46 and 47 are installed previously at the side face places of the RC beam 2 of the S beam 4, the S beam 4 is mounted by inserting a reinforcement 21 in a beam type frame 7 and the RC beam 2 is constructed by placing concrete and a joining section 5 is built. Consequently, a special mounting member is not used for constructing the S beam 4, the machining of the S beam 4 and the execution of works of the joining section 5 are facilitated, and simple and clear mutual mounting conditions are enabled, and further the fear of trouble in accuracy on the is hardly generated works of the S beam 4. Since member force and the quantity of a deflection generated in the S beam 4 are decreased, and the size of the S beam 4 is shrunk because of the S beam 4 as a continuous beam, the material cost of the S beam 4 and a construction cost for building the S beam 4 are reduced.
