In recent years, two new regulations regarding the design of steel structures, connections and structural elements have entered into force in our country: 1) Regulation on Design, Calculation and Construction Principles of Steel Structures - ÇYTHYEY, (2016); 2) Turkey Building Earthquake Code, TBDY : Chapter 9 – Special Rules for the Design of Steel Building Structural Systems Under the Impact of Earthquakes (2019). Among these regulations, ÇYTHYEY proposes a force-based evaluation and two design approaches (Design with Load and Strength Factors and Design with Safety Factors) in the design of steel structural elements and combinations. TBDY: In Chapter 9, there are principles of earthquake resistant steel structure design, in which significant changes were made after the 17 January 1994 Northridge earthquake.
With the entry into force of these regulations, the need for two types of resources regarding steel structure design has increased in our country: a) Examples of how the principles and design criteria in the regulations emerged and how they will be applied; b) Design tables and charts to assist engineers in practice. This handbook has been prepared to meet the second type of resource need. These design tables and charts, similarly prepared by the American Institute of Steel Construction, have been prepared in this handbook as design tables for European profiles that are widely used in our country.
The design tables in this handbook have been prepared for different steel grades in accordance with the Design with Load and Strength Factors (YDKT) approach, and the sections are organized as follows:
Ductility and compactness requirements,
Design of elements under bending and shear effect,
Design of elements under axial compression and tension,
Design of elements in compound bending effect.
It is thought that the tables in the book can be easily used by civil engineers in the design of steel structural elements, in the undergraduate and graduate level Steel Structures courses in the Civil Engineering and Architecture Departments, in project and homework studies.
In this first volume of the handbook, a limited number of tables of I-profiles have been created. In the second volume, which is being prepared, it is planned to prepare design tables for different profiles and cross-sections.
