水平力作用下高层复合板结构的性能分析和研究
|
摘要
我国建筑复合墙板的研究和工程应用是新兴的学科领域,对建筑业和建材工业的可持续发展意义重大。混凝土灌芯纤维石膏板(以下简称复合板)弥补了石膏板强度较低的问题,一改石膏板只能做非承重内墙的状况,不仅可以做建筑的内墙、隔墙,还可以做建筑物的承重墙与楼板。
为了更好的研究复合板在高层结构中的性能,本文在单块混凝土灌芯纤维石膏板计算的基础上,针对整个结构,依据复合板的构成特点,将石膏板与由芯柱和圈梁构成的框架(以下简称框架)分开,并用匀质链杆相连建立简化计算模型,得出均匀复合板结构(沿高度方向灌芯率相同)内力及位移的计算方法,并在此基础上,利用内力连续的计算方法,推导出不均匀复合板结构(沿高度方向灌芯率改变)情况下的内力及位移计算方法。按此方法对一较为典型的实际工程为实例进行计算,得到均匀结构灌芯率不同水平荷载情况作用下位移曲线,总结出一般情况下复合板结构水平位移的特征。同时将非均匀结构与均匀结构情况下的侧移图像进行对比,论证了采用不均匀结构的可行性。除此之外,本文还对石膏板与混凝土框架的塑性性质进行了近似分析,进而对复合板结构的破坏过程进行计算,为以后该材料进行广泛应用提供了较为合理的简化计算方法。
The engineering application and mechanical analysis of concrete frames with fiber plasterboard (referred as composite board below) in our country is a new domain which has a major significance for the sustainable development in construction and building materials industry. Composite board makes up for the low strength of gypsum plank, so it is not only used in internal decoration such as ceiling suspension, or in non-structure components such as nonbearing walls, but also used as main wall.
In order to make a further research of the composite board’s performance in high-rise structure, according to the structure characters, the author sets up the calculating diagram in the way that depart the plasterboard and the frames consisting of concrete core and ring beam away, and join them together with isotropic chain-pole. This paper presents a method for calulating the internal force and displacement of a uniform structure(same concrete-filled styles on the vertical)and non-uniform structure(different concrete-filled styles on the vertical). Through the calculation for a typical experimental structure, the displacement curve of different concrete-filled styles under various horizontal loads can be obtained .Then the author derives the feature of displacements under normal curcumstances and demonstrates the feasibility of using non-uniform structure. The paper also makes an approximate analysis of concrete core and plasterboard’plastic properties respetively, then the failed process of the composite board can be deduced. This paper provides a more reasonable simplified calculation method for wider application.
