Reducing self-weight and improving toughness is always a subject that modifying the common concrete since it is come into being , the steel fiber reinforced concrete pathed the way for improving the toughness of it ,while the lightweight concrete solved the problem to the heavy dead weight.

混凝土自从问世以来，减轻自重、提高韧性一直是对其改性的课题，钢纤维混凝土为改善韧性开辟了道路，而轻骨料混凝土则解决了其自重大的问题。

These tendons also can assume the moments at the end of the beams in ordinary condition. By way of these tendons, precast beams and columns can be assembled conveniently, and the joints and frame are monolithic and continuous. Consequently, compared with common reinforced concrete frames, this kind of frame systems possess higher reliability and solved the problems in the process of assembling Prestressed Concrete frames. Also it forms the framework of Prestressed Subassemblage concrete frame, and explores a new way for industrial production of prestressed structures.

后张预应力筋既可作为施工阶段拼装手段，又可在使用阶段承受梁端弯矩，构成整体受力节点和连续受力框架，克服了装配式节点受力可靠性差的缺陷，解决了预应力混凝土框架难以装配的问题，形成预制预应力混凝土装配整体式框架，开辟了预应力结构工业化生产的新途径。

基于理论分析，本文主要对钢管高强混凝土柱—变宽度钢筋混凝土梁节点进行了三维有限元数值模拟计算。

The paper reviews the experimental results of chloride permeability of reinforced concrete cover based on ASTM C1202,and states that the resistance of ordinary marine concrete against chloride penetration is poor and the performance of concrete against chloride penetration can be remarkably improved by admixing with silica fume .

描述了按A STM C 1202方法试验研究保护层混凝土的氯离子渗透性能，指出以往普通港工混凝土的抗氯离子渗透性能较低，而掺入硅灰能显著提高混凝土的抗氯离子渗透性能。

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。
