Abstract

In planning a structure, the first thing which should be done by an engineer is the utility and function of which is being designed related to the load, especially earthquake load. Therefore, a structure specialist will devise a way how to pattern various styles of element which will be transferred to specific points. In technical mechanics, it is explained that inertia of a pro.file highly determines the choice of pro.file dimension which be used. This is because of the variation and load direction is varied in each construction. Inertias of hollow steel pipe has the same value for all directions so that it will be stronger in carry the load than the other pro.files. The problem faced by the writer during his work was the problem of connecting; in connecting a pipe with pro.file one used the same type of pro.file, using welding. In this thesis, the writer attempted to make an experiment of connecting a hollow steel pipe with Wide Flange pro.file by using external diaphragm plate in order that in the connecting area there would be semi stiff behavior by using bolt as the connector with gradual loading until the bolt melted. There were two specimen used in the experiment: using stiffener and not using stiffener. Each experiment was compared with Finite Element Method (FEM) program. The percentage of additional load because of the stiffener was 34.61% and the difference in deflection was 40.58%, while the percentage of the increase in stiffener in the result of the experiment was 157.39% and the result ofhe Finite Element Method (FEM) was 159.20%.
