Title :安全荷重域に関する研究1

Abstract :Studies on safe-domain were made by Dr. Prager and Dr. Futami. Concept of the safe-domain of rigid framed structures, how to seek for it, and furthermore, design by it has been made public. This paper, on the basis of these thesis, is a study of the character of safe-domain from the standpoint of plastic collapse load design. After pointing out that the border-line of safe-domain is nothing but virtual work equation of collapse mechanism plotted on the load plane, virtual work equations of collapse mechanism were sought for and a method of seeking for safe-domain by means of plotting them was proposed. Its reasenableness was proved by use of the devised theorem. Following that the safe-domain which covers design load plotted on load plane was established, conditional equations which can be sub-stantiated among critical sections of rigid framed structures were formulated by use of the fact that the border-line of safe-domain is the virtual equation of collapse mechanism. Here proposed a new plastic collapse load design in which conditional equations were solved simultaneously and value of the full plastic moment on each critical section was assigned.
