大跨度PK预应力混凝土叠合板的试验研究与理论分析
|
摘要
大跨度PK预应力混凝土叠合板是在对已有普通PK预应力混凝土叠合板进行改进的基础上,研究出的一种新型大跨度叠合楼板结构。该叠合板的预制构件为预应力混凝土预制薄板,板上带有“T”形肋,肋上预留长方形孔,孔内可布置横向穿孔受力钢筋,叠合层混凝土浇注后可形成单向预应力双向受力叠合楼板,该楼板具有承载力高、整体性和抗裂性好,节约钢筋和模板、缩短工期等优点,工程应用前景广阔。
本文在现有普通PK预应力混凝土叠合板的基础上,对大跨度PK预应力混凝土叠合板进行了初步的研究,主要研究内容有:
(1)对叠合板的预制构件和叠合构件进行截面设计及静载试验研究;
(2)利用有限元分析软件对该叠合板的试验构件和整板进行非线性有限元分析;
(3)利用正交各向异性板理论对该叠合板进行弹性分析,并提出该叠合板的弹性设计方法;
(4)利用塑性绞线理论对该叠合板的塑性极限承载力进行分析。通过预制构件和叠合构件的静载试验及有限元分析,研究了大跨度PK预应力混凝土叠合板预制构件和叠合构件的承载力、刚度、整体性和抗裂性能,证明了该叠合板预制构件和叠合构件具有较高承载力和刚度,可以满足实际工程应用的要求。
通过叠合整板的有限元及弹塑性理论分析,证明了大跨度PK预应力混凝土叠合板不但具有较高的承载力和刚度,且在弹性受力阶段叠合板的预应力方向和非预应力方向的抗弯刚度相差很小,楼板的双向受力特征与普通现浇钢筋混凝土双向板基本相同,可按普通现浇双向板对其进行计算分析。
Large-span PK prestressed composite slab is a new composite floor structure proposed by improving the common PK prestressed composite slab. The prefabricated component of the slab is a prestressed ribbed panel and has preparative holes on its“T”shape rib. When the transverse imprestressed reinforcing steel bars through the rib’s rectangle holes are collocated, a prestressed two-way composite slab is formed after the concrete cover is casted. This slab has merits of good integrity and crack resistance, high bearing capacity and low building costs, and therefore its application future is very expansive.
Based on the research production of common PK prestressed composite slab, preliminary studies of large-span PK prestressed composite slab have been done in this thesis. The major researches are as follow:
(1) Sectional design and static test of prefabricated components and composite elements;
(2) Nonlinear finite element analysis of tested components and integral slab;
(3) Elastic analysis based on orthotropy slab theory of this composite slab and suggestion for elastic design method of it.
(4) Ultimate bearing capacity analysis of this composite slab based on the plastic hinge line theory.
Through the static test and finite element analysis of the prefabricated components and composite elements, the bearing capacity, rigidity, integrity, and crack resistance of the prefabricated components and composite elements have been studied in this thesis, and this thesis also proved that the prefabricated components have relatively high bearing capacity and rigidity which will suffice the requirements of practical application well.
Through the finite element analysis and studies based on elastic and plastic theoryies of the integral composite slab, this thesis confirmed that the large-span PK prestressed composite slab not only has relatively high bearing capacity and rigidity but also has little difference between the flexural rigidity of prestressed and non-prestressed direction at elastic stage, and the two-way forced characteristics of this slab is the same as the ordinary cast-in-situ reinforced concrete two-way slab, and can be analysed by the same theory.
