靜不定結構（statically indeterminate structure）是工程力學中的專業術語，指僅依靠靜力平衡方程無法完全确定所有内力或反力的結構體系。其核心特征在于結構的未知力數目超過獨立平衡方程的數量，需借助變形協調條件或能量原理進行補充計算，例如美國土木工程師學會（ASCE）在《結構分析基本原則》中指出“靜不定性源于約束冗餘，這類結構對溫度變化、支座沉降等外部因素更敏感”。
該概念可通過與靜定結構的對比加深理解：
典型應用場景包括：
國際标準《Eurocode 3》第5.2.3條款強調，超靜定結構設計必須同時滿足強度、剛度、穩定性三重驗算标準。這類結構的優勢在于内力重分布能力強，但需要更複雜的有限元分析工具支持，如ANSYS等工程軟件常采用力法或位移法進行超靜定次數判定。
statically indeterminate structure（靜不定結構/超靜定結構）是結構力學中的專業術語，指無法僅通過靜力學平衡方程确定所有約束反力和内力的結構系統。以下為詳細解釋：
靜不定結構因存在多餘約束（多餘約束數目稱為“靜不定次數”），導緻僅用平衡方程無法求解全部未知力。例如，一個具有固定端支撐的梁若存在中間支撐，可能因多餘約束成為靜不定結構。
根據多餘約束的位置，可分為：
靜不定次數等于多餘約束數目，可通過以下公式确定： $$ n = C - (3 times m) $$ 其中，( C )為總約束數，( m )為獨立剛體數（如單跨梁( m=1 )）。
如需進一步了解具體結構的分析方法或工程案例，可參考結構力學教材或專業文獻。
