In this paper, based on analysis of existing experiments and examples related to prestressed concrete slab system and finite element method, some problems in prestressed concrete beamless slab and reinforced concrete two-way slab supported by beam as the following items are studied.

本文对以往预应力混凝土板系的有关试验及例题进行分析，结合有限元方法对预应力混凝土无梁板及梁支双向板重点研究了以下内容： 1。

So we suggest in design of the jacketing steel reinforced concrete frames prestressed with bonded tendons for storey-adding, in the area of earthquake fortification intensity of degree 8, steel reinforced concrete frames prestressed with bonded tendons situated in Class II and III soil with the height of ground floor is 8.1m and the number of added stories is 2 to 4, multiplying coefficient of bending moment of column, detail of seismic design of beam, column, and joint, should conform to a higher one earthquake-resistant grade.

建议套建增层预应力钢骨混凝土框架结构设计时对于8度抗震设防区建造在II、III类场地土上的底层结构层高为8.1m，增层层数为2层到4层的原二级抗震框架其柱端弯矩增大系数及相应的梁、柱、节点的抗震构造措施应按一级抗震框架取用。

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。

Decades, the system does not always produce pipes, tiles, cement products and other traditional rod, but the development should be high (high-strength, high pressure) and large, new (new building materials and products) as a key to develop new products In detail: to develop high-strength prestressed concrete pile; apply to set up more than 110 kilovolt high voltage transmission lines and electrified railway lines, etc. Catenary large t m poles; application of new high-speed heavy rail with pre-stressed concrete sleeper; high-pressure , large-diameter prestressed concrete cylinder pipe; steel concrete and prestressed steel-concrete composite pipe; new type of reinforced concrete pipes, such as the mouth and socket bearing steel reinforced concrete pipes, square pipes, short-shaped pipes, common drains ; reinforced concrete inspection and; urban and rural construction using a variety of hollow interior wall panels and composite wall panels, concrete hollow block.

不能几十年一贯制生产管、瓦、杆等传统水泥制品，更应把发展高、大、新作为重点开发新产品，具体讲：大力发展预应力高强混凝土桩；适用于架设110 千伏以上高压输电线路和电气化铁路接触网线路等的大吨米电杆；适用高速重载铁路用的新型预应力混凝土轨枕；高压、大口径预应力钢筒混凝土管；钢板混凝土和预应力钢板混凝土复合管件；新型钢筋混凝土排水管，如钢承口和承插式钢筋混凝土排水管、方型渠、短形渠、共同渠；钢筋混凝土检查并；城乡建设用的各种空心内墙板和复合外墙板、混凝土空心砌块。
