In order to quantitatively analyze the aseismatic performance of this kind of beam-column assemblies through whole loading history, the non-linear FE analyses of the cross beam-column specimens were carried out by ANSYS. Compared to the experimental results, the finite element analyses cast a further light upon the characteristics of this beam-column assembly while being subject to cyclic reverse loading.

Special Shaped Column's space framework, the computer program of its disposition of reinforcing bar and the economic quota analysis of the design.

本课题设计的主要内容是对一个三层现浇钢筋混凝土异形柱空间框架结构进行变形与内力分析，并编制"L"形钢筋混凝土异形柱的配筋计算程序，然后对该结构的"L"形截面柱进行配筋设计与分析，最后对该工程设计进行经济指标分析。

In the construction of frame structure using reinforced concrete, we often meet a few problems as follows:(1) The thickness of concrete sheltering layer;(2) Different concrete has different intensity grade;(3) The construction of beam nodes by hooping the steel bar;(4) How to anchor the side pillar of the room surface by using steel bar.

In this paper, the baroclinic pole in baroclinic theory is supposed to be membrane-element subjected to shearing stress and normal stress in plain section. With the help of truss model, it meets the equation of two-dimension stress, Moire's strain corresponding equation and double-axis intenerate strain-stress relationship of concrete. It describes the load-behavior and working property of reinforced concrete combined torsion members in the whole load-deformation process.

本文将斜压场理论中的斜压杆表达成在平面内承受剪应力和正应力的钢筋混凝土薄膜元，借助桁架模型，满足二维应力平衡条件、莫尔应变协调条件和混凝土的双轴软化本构关系，揭示钢筋混凝土复合受力构件在受力-变形全过程中受力行为和工作性能，为研究复合受扭构件的变形行为打下了坚实的基础。

Because the top of concrete platform of the carbide furnace has big spans and it carries a heavy load,the scheme of the strengthening concrete with trifurcate beam is used in the structure.

电石炉本体上部钢筋混凝土平台因承受的荷载大、工艺要求的跨度大，采用了劲性混凝土三叉梁的方案，文章针对这一新型结构形式的施工，从方案选择、钢筋接头设置、钢结构制作、灌浆和安装，以及钢纤维混凝土等主要方面进行了介绍。

HRB400 steel bars, the 400 MPa hot rolled steel bar, which is called new grade III steel bar, has been taken as the one of 10 new technical spreading the application mainly, listed in revised newly code, so spread application as leading steel bar in reinforced concrete structure.

HRB400级钢筋已作为高效钢筋被列为重点推广应用的建筑业10项新技术之一，早在1998年建设部就明确提出：&新Ⅲ级钢筋是专门为建筑结构应用开发的新型钢筋，该钢种已列入新修订的国家规范标准，应大力推广使之成为我国钢筋混凝土结构的主导钢筋&(建设部建[1998]200号文)。

Taking the 1#'s coal trestle in the coal-smashed engine room of Shenyang thermal power plant which was set up in 1958 for example, it is discussed that when fall-off height of concrete in drawing district of reinforced concrete structural member harmed seriously in flexure increase, the bond performance of reinforcing bar and concrete deteriorate continuously and the time-dependent regulation of the weight force and deformation of structural member. Dynamic reliability indexes before and after consolidation is obtained by the method.

鉴于现行的可靠性鉴定标准与结构设计标准不相协调，仅从定性的角度给出了结构构件和系统的可靠性要求，以始建于1958年的沈阳热电厂碎煤机室1＃甲输煤栈桥为例，讨论了受损严重的钢筋混凝土受弯构件随拉区混凝土脱落高度的增加、钢筋与混凝土之间粘结性能不断劣化，构件承载力及变形的经时规律，并求得加固前后动态可靠指标，使得可靠性鉴定结果更具科学性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
