在深入研究已有钢筋混凝土组合与均匀二类单元，发现普遍存在没有充分考虑到钢筋实际作用的问题，从而导致了计算结果过于保守后，本文首先针对钢筋混凝土的构造特征，提出了同一位移场与非同一位移场的概念。

According to the deterioration mechanism of concrete, the model of life perdiction in the corrosion form of corrosive medium and high heat were based on the penetration of chloride with the rustiness of steel and the carbonization of concrete with the rustiness of steel. The calculation results of service life of the origin concrete and new mending materials were close to the actural phenomenons.

根据两种腐蚀形式的劣化机理，建立以氯离子渗透和钢筋锈蚀以及温度影响下的混凝土碳化和钢筋锈蚀为主体的钢筋混凝土使用寿命预测模型，并分别对原有材料和新修补材料进行使用寿命预测，预测结果与实际工程相吻合。

It provides a basic theory for the deformation property of combined torsion members. With the method, this paper, for the first time, discusses the nonlinear complete process analysis of high-stress concrete members subjected to combined force. It revises the strain-stress relationship contain of intenerate of concrete and simplifies the baroclinic theory of concrete. The calculation result fits the test result well, which proves that membrane-element theory is suit to reinforced concrete combined torsion members.

应用这种方法，本文首次对高强钢筋混凝土压弯剪扭复合受力构件进行了非线性全过程分析，对考虑软化的混凝土本构关系进行了修正，对混凝土斜压场进行了简化，经分析计算与试验结果对比符合较好，说明薄膜元理论对钢筋混凝土复合受扭构件受力行为的全过程分析是一种有效的方法。

本文根据对&双钢筋混凝土&小梁的试验资料的分析，提出了在普通钢筋混凝土受弯构件中采用经过构造处理后形成的&梯格状钢筋网&即&双钢筋&的可行性。阐述了双钢筋构件的强度、裂缝及变形的特点。

Through the test of 8 RC shear wall specimens and the computer analysis of the strains of steel bars with keyways in the spccimens, the authors have studied the remains of tensile stress of concrete between cracks after cracking and put forward a formula to calculate coefficient ψ, the ununiform distribution factor of steel strain.

本文通过8片剪力墙板的试验，用计算机对各级荷载下钢筋连续应变值的分析，找出了钢筋混凝土剪力墙板开裂后裂缝间混凝土受拉性能的变化规律。给出了钢筋应变不均匀系数ψ的计算公式。

In pure torsion members with high strength concrete and over reinforcement, the bars willnot yeld, the surplus bar will be extravagant.

在钢筋混凝土和高强混凝土超配筋纯扭构件中，由于配筋量过高使钢筋不能屈服，引起钢筋用量过多而产生材料的浪费。

In 1998,its pointed new grade III steel bar is a new type building steel used specially in building structure.

而且新颁布的《混凝土结构设计规范》GB50010-2002中，也明确提出将HRB400级钢筋作为钢筋混凝土结构的主导钢筋。

In the static test on Yi'an Bridge in Chongyi,we take a detailed examination and analysis about the flexivity、reinforcement stress、concete stress、steel wires stress of the steel-reinforced concrete、the low prestressing concrete and the full prestressing concrete on the twenty-meter long beam.

在崇义义安桥的静载试验中，对20 米标准跨径的普通钢筋混凝土、低预应力混凝土、全预应力混凝土空心板梁在均布荷载作用下的控制截面的挠度，钢筋、混凝土、钢绞线的应力作了较详细的试验、分析。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
