In order to enrich and perfect the exisiting theory research achievements , and promoting the application of staggered truss steel framing system in our country , static force capability , stability problem and structure p - a effect have been done in this text ; combines current national design code ( specification ) and abroad research achievements , propose the elastic design methods and suggestions of the staggered truss steel frame 為了充實和完善現(xiàn)有理論研究成果,促進鋼結構錯列桁架體系在我國的工程應用,本文對鋼結構錯列桁架體系的靜力性能、穩(wěn)定問題、結構p -效應作了系統(tǒng)性的分析;并結合現(xiàn)行國家設計規(guī)范(程)和國外研究成果,提出了鋼結構錯列桁架體系的彈性設計方法和建議。
On the basis , three elastic calculation coefficients of the two - way composite slab on three common boundary conditions are deduced and calculated by applying the classic elastic plane theory . in the thesis , the elastic design methods of pk prestressed composite two - way slab is explored and studied by the example . furthermore , it is also studied how to apply the yield - line design method to design the prestressed two - way composite floor slabs 本文以此為依據(jù),應用經(jīng)典彎曲薄板理論,采用李維法推導和計算了這種雙向樓板三種常見邊界下的撓度和內(nèi)彎矩彈性計算系數(shù),并在此基礎上通過算例探討了pk預應力雙向疊合樓板的彈性設計方法,同時還對其塑性鉸線設計方法進行了研究。
When the elastic design method is used , the paper proposes the recommendation that designer can not consider second - order effect on structural internal force , but must consider the effect on drift computing , and also gives a simplification method for calculating the second - order drift . base on above research achievements and referencing current design codes and research documents , this text has done overall discussions on the elastic design method , the chief works includin 基于前面的研究成果,參考現(xiàn)有各國鋼結構設計規(guī)范和已有的研究文獻,本文首次對鋼結構錯列析架體系的彈性設計方法作了全面的探討,主要工作包括材料的選用、構件截面形式、構件彈性設計方法、連接節(jié)點設計和構造詳圖、組合樓蓋的設計、栓釘剪力連接件的設計。
