橋樑載重分析設計軟體

STAAD.beavaBridge Engineering Automated Vehicle Application可以在STAAD.Pro環境中供計算橋樑設計載重之解決方案。

STAAD.beava使用3D影響面(3D influence surfaces),可以針對元素應力,桿件撓曲彎矩、節點變位,支承反力自動產生影響面分佈圖,經由STAAD.Pro分析計算載重,及利用設計規範(UK BS5400 , AASHTO 2000),計算車道、影響線、荷載長度、集中載重臨界位置、UDL與車道載重,以及最大與聯合作用影響值。所有結果皆顯示為圖像化。

橋樑設計規範必須獲得想要的最大效應,故需依車道上的載重長度、車道係數與載重密度等各項條件,採用錯誤嘗試法(trial and error),在測試各種載重狀況後,才可以獲得最大設計效應﹔,Research Engineers International發展STAAD.beava,係遵守國際標準規範並縮小獲得載重最大效應過程的時間,使用者可減少許多計算工作量。

若將STAAD.beavaSTAAD.Pro整合,使用者可利用STAAD.Pro的功能處理模型輸入與顯示結果,輸入與輸出資料皆採用相同的GUI(圖形化使用介面)。由STAAD.beava計算之移動活載重資料可移轉為STAAD.Pro的載重狀況(load case),移動活載重與靜載重效應可結合,包括風力與地震亦可。

STAAD.beava依據工程師選擇的設計規範,在橋樑模型上定義行車道(Carriageway)與車輛載重(loading arrangement),程式自動產生3D影響面圖,橋面板之影響面效應會各別的影響面圖,顯示最大與最小值及產生結果的活載重資料。

工程師可定義行車道形式與車道寬度,行車道可為多車道、筆直、弧形車道,車道寬度亦可不同,STAAD.beava內建車輛載重規範有AASHTOBS5400等,使用者亦可自定車輛載重

STAAD.beava, the Bridge Engineering Automated Vehicle Application, is an integrated solution inside the STAAD.Pro environment.  STAAD.beava uses 3D influence surfaces, which are generated by STAAD.Pro as part of the loading process.  STAAD.beava will automatically generate influence surfaces for effects such as bending moments on members, support reactions, element stresses and nodal deflections.

 

FINALLY, A COMPLETE BRIDGE ANALYSIS AND DESIGN PACKAGE

Introducing the New Bridge Loader Module for STAAD.Pro

STAAD.beava

Fully integrated with STAAD.Pro

 

Prior to STAAD.beava, the process of load application for a bridge deck was complex since governing rules can impose inter-dependant parameters such as loaded length on a lane, lane factors and load intensity. To obtain the maximum design effects, engineers had to try many loading situations on a trial and error basis.

STAAD.beava helps to reduce the frustration from the trial and error process and then proceeds to follow the selected design code and calculate the number of traffic lanes, influence lines along the centerline of the traffic lanes, loaded length along the lanes, critical locations of all knife, UDL and vehicular loads, and the maximum and associate effect values. All results are displayed graphically including the critical position of the vehicle along the traffic lanes.

All relevant code instructions for loading definitions and traffic lane calculations are incorporated in STAAD.beava, and in cases where vehicle axle arrangements are not standard, it is possible to define a vehicle and save it in the library for future analyses.
