CSI SAP2000 v15.2.1 Ultimate-LAV (2013)-結構通用有限元計算軟件 SAP2000V15對於中國用戶的最重要改進是更新至國內最新的結構設計規範,包括目前已近發佈實施的《混凝土結構設計規範(GB50010-2010)》、《建築抗震設計規範(GB50011-2010)》、《高層建築混凝土結構技術規程(JGJ3-2010)》三本規範的相關內容。相應地,程序對於地震荷載、荷載組合、材料特性、混凝土框架設計和鋼框架設計等內容都按照新規範的規定進行更新。此外,SAP2000V15自身的增強特性及其它國家規範的更新內容列舉如下: 圖形用戶界面新增選項卡式窗口 新的DirectXgraphics 顯示和輸出框架截面應力 荷載優化功能,以確定最佳的荷載比例,實現整個結構的位移和力響應的 目標和限制 內置歐洲混凝土和鋼的材料特性 加拿大NBCC風、地震、反應譜荷載 美國ASCE-7風、地震、反應譜荷載 意大利NTC2008帶有地理數據庫的反應譜函數 印度鋼框架結構設計規範IS8002008 新西蘭鋼框架結構設計規範NZS3404-1997 加拿大鋼框架結構設計規範CSAS16-2009 更新香港混凝土框架結構設計規範包含Supplement1 澳大利亞混凝土框架結構設計規範AS3600-2009 增強歐洲規範3-2005鋼框架結構設計,包括Class4截面設計 歐洲規範2-2004混凝土框架結構設計的國家附件,新加坡,德國,和葡萄牙 混雜鋼框架截面屬性 簡單的鋼筋弧線輪廓定義 更新API功能 導入StruCAD*3D設計參數和波浪加速加載 橋樑模塊被移至帶有擴展功能特性的產品CSiBridge,仍保留基本的移動荷 載分析。 其它一些小改進 ------------------------------------------------------------------------------------------------------ AP2000isgeneral-purposecivil-engineeringsoftwareidealfortheanalysisanddesignofanytypeofstructuralsystem.Basicandadvancedsystems,rangingfrom2Dto3D,ofsimplegeometrytocomplex,maybemodeled,analyzed,designed,andoptimizedusingapracticalandintuitiveobject-basedmodelingenvironmentthatsimplifiesandstreamlinestheengineeringprocess.
