Economic Comparison and Ductility Assessment ofMembers Made from High-Strength Steel and Conventional Steel

الملخص

 Abstract
The use of high-strength steel in steel structures has increasingly
attracted attention due to its desirable mechanical properties and the
reduction in structural weight. This study provides a comprehensive
comparison between structural members made of conventional steel
and high-strength steel from an economic and ductility perspective.
The findings indicate that utilizing high-strength steel can lead to a
reduction in weight and cross-sectional dimensions, thereby
decreasing material and transportation costs. However, the ductility
and seismic behavior of members constructed with high-strength
steel are more limited compared to conventional steel, which may
directly affect the safety performance of structures under seismic
loads. In this research, the results of an economic analysis and the
evaluation of ductility behavior of structural members made of these
two types of steel, based on library research methods, are presented.
The impact of steel type selection on structural design and final
performance is discussed. The findings demonstrate that choosing
the appropriate steel type must consider functional requirements,
seismic conditions, and economic considerations.
