Where we find any reflections at all determines the lattice type . 只要最终发现任何反射,就可确定点阵类型。
Therefore , it is necessity to continue to study the lattice type src 因此,对于空腹式钢骨混凝土的研究仍是很有必要的。

The truss type steel reinforced concrete is a pattern of the lattice type steel reinforced concrete . it is regarded that the seismic behavior of the truss type src is lower than the full - web type src members 桁架式钢骨混凝土是空腹式钢骨混凝土( steelreinforcedconcrete ,以下简称src )的一种,一般认为其抗震性能不及实腹式src构件,而与普通钢筋混凝土( reinforcedconcrete ,以下简称rc )构件基本相同。
In structure design , the value of axial compression ration of src columns has influence not only upon the seismic behavior of structure , but also upon the section dimension , steel requirements and seismic behavior . at present , the definition of the limited values of axial compression ration in the design specification of src structure and other research on a xial compression ration is focus in the full - web type src columns . but there is fewer data about lattice type src members 在结构设计中,钢骨混凝土柱轴压比的取值不仅对结构的抗性能有很大影响,同时也是确定柱子的截面尺寸、钢骨含量及抗震配筋构造等的重要依据,目前,钢骨混凝土结构设计规程中对轴压比限值的规定和其它有关轴压比的研究主要是针对实腹钢骨的,目前尚无空腹式钢骨混凝土方面的资料可供参考。
To analyze the seismic behavior of the lattice type src members , look for a section patterns which is not only safety but also economic , in this paper , a experiment of seismic behavior about nine truss type src columns and three rc columns which strength , steel requirements and axial load are different , the deformation capacity and failure patterns are observed , and the hysteretic cycle are obtained . according to the experiment results , it is different between the failure patterns of src members and rc members 为了分析空腹式钢骨混凝土的抗震性能,寻找一种即安全又经济的src截面形式,本文对9根不同强度、不同配钢率、不同轴力的src试件和3根普通rc试件做了抗震性能试验,在保持轴力不变的情况下,采用荷载? ?变形混合控制方法施加往复的水平荷载,观察其变形性能与破坏状况,测得各试件的滞回曲线。
Throught the comparation between supsendome and single layer reticulate , the advantages of suspend - dome was expatiated . through the analysis of lamella ’ s , rib - loop , rib - loop tilted bar type shell , the influence of lattice type to member ’ s force , joint ’ s displacement , reaction , intergral stability was studied , the suitable lattice type for suspendome was put forward 通过对联方型、肋环型、肋环斜杆型、肋环斜杆型、肋环斜杆型弦支穹顶结构进行的分析优化比较,研究了网格形式对构件内力、节点位移、支座反力、整体稳定的影响,提出了适合弦支穹顶结构的合理网格形式。
Because the truss src members includes steel , the ultimate flexural strength of those is more increased than the reinforced concrete ( rc ) members . on the other hand , it is often that in the application the contradiction of steel between beams and columns can not be solved , the lattice type src columns is proposed in this case 不过,与普通钢筋混凝土结构相比,空腹式src结构由于配置了钢骨,大大提高了构件的承载力,另一方面,对于实腹式src构件,在实际应用中经常遇到无法解决梁与柱交叉穿筋的问题,这时,宜采用空腹式钢骨混凝土。
