CSI Bridge 2015 v17.3-橋樑結構的建模分析和設計工程軟件
CSiBridge2015集成了橋樑結構的建模、分析和設計，是一個無比強大的工程軟件工具。所有的任務都能方便快捷地實現，使得CSiBridge成為當今市場上最通用和最具生產效率的軟件產品。

使用CSiBridge，工程師可以方便地定義複雜橋樑的幾何、邊界條件及荷載工況。橋樑模型是參數化定義，使用橋樑工程師熟悉的術語，例如佈局線、橋跨、支座、橋台、橋墩、橋鉸以及後張預應力等。軟件可以生成三種分析模型：主梁模型、殼模型、實體模型，當橋樑定義參數發生改變時，自動更新相應的分析模型。

CSiBridge可以方便快速地對鋼橋和混凝土橋進行設計和改造，參數化的建模器使得用戶可以創建簡單或複雜的橋樑模型，高效地進行修改，對整個設計過程保持完全控制。可以快速定義車道和車輛，包括寬度效應；簡單實用的甘特圖可用來模擬施工順序和計畫。

CSiBridge包含了一個方便的建模嚮導，概括了創建橋樑模型所需的主要步驟。

在CSiBridge設計包裡完全集成了SAPFire®分析引擎，包括施工順序、徐變和收縮分析、索張拉到目標力、起拱和找形、幾何非線性（P-delta和大位移）、材料非線性（上部結構、支座、下部結構和地基土支座）、屈曲、靜力和動力分析等。所有這些應用到單一的複雜模型。而且，還包括了AASHTOLRFD和中國橋樑設計規範，可以進行自動荷載組合、上部結構設計和抗震設計。
