補正係数による頭付きスタッドの終局せん断耐力式の提案

Abstract

This study proposed the new method of the ultimate shear strength of headed stud by multiplying simply modified coefficient to the design formula. In the first step, the database of ultimate shear strength and some elements affected the strength are organized. Based on the multiple regression analysis on some main elements in database, the modified coefficient is each created separately by slab detail. The modified formulas both in case of flat slab and deck slab are improved the accuracy of ultimate shear strength than design formula.
