Summarizing the above - mentioned research results , the design method of two kinds of connection ways of steel braces is proposed , which include the calculation formula of the steel braces , the head studs , steel angels at four corners of beam and column and embedded steel framework 本文在上述試驗的基礎上,提出了兩種支撐加固連接方式的計算公式,包括支撐桿件、栓釘、外包鋼連接和鋼內框連接等。
Here the hsc of sompa is achieved through adding super - effective water reducer , fined slag and silicon fume , and decreasing the water / cement ratio . by varying the area ( spacing ) of tension bars , compressive bars , vertical links and distribution steel and embedding steel fiber and polypropylene fiber we try to improve the behaviors of reinforced high performance concrete one - way spanning slabs in bending , so that its ductility be greater than 5 . with the same arrangement of steel the width of bending member is varied to observe the effect of the width / depth ratio on the ultimate compressive strain of concrete 通過變化受拉筋含筋率和受壓筋、箍筋(鉤筋、分布筋)含量,或摻加纖維使之成為鋼纖維高強混凝土( sfrhsc )和聚丙烯纖維高強混凝土( pfrhsc ) ,對高強混凝土雙筋截面梁、板的受彎性能進行了試驗研究,試圖改善高強混凝土受彎構件的延性,使其延性比大于5 ;并在相同配筋情況下,通過變化截面寬度,研究了高強混凝土受彎構件的寬高比對壓區(qū)混凝土極限應變的影響;并對試驗構件的裂縫發(fā)展情況進行了觀測。
In this paper , mechanism of embedded steel framework is analyzed . the steel framework has superiority in load - bearing capacity as a self - equilibrium system . we can draw from analysis that the embedded steel framework can be designed according to the criterion of steel - concrete composite structures 本文還對鋼內框的受力機理進行了探討,鋼內框作為一種自平衡體系在傳力機理上有其優(yōu)越性;鋼內框的設計可以按照型鋼?混凝土組合結構來計算,本文提出了鋼內框的構造。
