6月4日上午，賓夕法尼亞州立大學陳幼佳教授應邀來到我院，在明志樓A536為師生們帶來了一場題為“Structural steel design - AISC versus GB: Principles and examples（鋼結構設計—AISC與GB對比：原理與示例）”的精彩學術報告。本次報告由我院院長甘丹教授主持，吸引了眾多青年教師和研究生的參與。
報告伊始，陳幼佳教授以2023版美國AISC LRFD（荷載和強度系數設計）與2017版中國GB 50017（鋼結構設計標準）為核心，介紹了兩者的設計理念。AISC LRFD設計基于概率論方法，強調通過荷載與抗力因子實現安全性與經濟性的平衡；GB規范則更傾向于采用統一的強度設計值，簡化了計算過程，但可能在某些情況下導致設計偏保守。為直觀展現中美規范在工程實踐中的差異，陳教授列舉多個具體案例，詳細對比了二者在應力計算、穩定性校核及螺栓連接設計中的不同。例如，在相同荷載條件下，GB規范對螺栓連接的設計要求比AISC高出約28.7%，而在焊接連接中，GB的保守性甚至可能達到42%。陳教授強調，這種差異源于兩國規范對安全儲備、材料性能及施工工藝的不同考量。
最后，陳幼佳教授與現場師生就如何在實際工程中選擇合適的規范、如何優化設計以提高經濟性等問題展開了熱烈討論。陳教授表示，隨著全球化進程的加快，中美規范的融合趨勢日益明顯，工程師應具備跨規范設計的能力，并結合項目特點靈活應用。本次講座為師生提供了寶貴的國際視野，促進了中美鋼結構設計規范的交流與學習，對理解中美鋼結構設計差異具有重要意義。
