Abstract: Sufficient yield strength is achieved against tensile, compressive and shearing forces working on steel frame columns and steel frame girders by using simply configured connective fittings to reduce costs and construction periods. For this purpose, a connective structure of highly rigid steel frame columns and steel frame girders formed by connecting steel frame columns and steel frame girders each having a web part and flange parts with connective fittings is provided. Each of the connective fittings has a bottom plate part and, on a surface of the bottom plate part, side plate parts which rise at a substantially right angle to the bottom plate part and have inserting areas extending farther than a tip of the bottom plate part in the state of rising at the substantially right angle.

Abstract: An integrated building production information system including design CAD (computer-aided-design) based on software of building, structure, and equipment, and databases built in the outside separately from the design CAD, the databases making an integrated DB (shared database)-CAD system of building, structure and equipment as an execution-linked system in DB-CAD's sharing of a standard database, wherein the integrated building production information system stores the information made compatible by three-dimensional superposition at the time of design into a shared database (DB) of the integrated DB-CAD system, and further receives and links information of this shared database to extemal systems such as a skeleton drawing CAD, a reinforcing bar and steel frame system and the like and produces execution information.

Abstract: According to the invention, by developing a function of linking pieces of information of CAD's with one another for improving design drawings in quality, the pieces of information can be unified, the compatibility of information can be obtained or the efficiency of a collating operation can be improved and thereby data being compatible and good in quality which are made at an execution design stage can be obtained and a work of taking the compatibility can be advanced and further can be performed easily in a short time, and, therefore, such effects lead to shortening of the whole process and furthermore make it possible to comprehensively improve the efficiency of building production by diverting and utilizing said data at estimation and execution stages after the execution design stage.
