Shell-Slab Without Rib and Its Application in the East Part of the North-West in China

本文论述了无肋大板的产生、变厚度横断面无肋大板的特点、设计方法和试验结果,以及充分利用双曲抛物面特性的无肋大板施工要点。最后用工程实例说明了无肋大板在西北东部地区中小型工业厂房、大中型公共建筑和农村住房中的应用。这些应用均取得显著经济效益。

The production of shell-slab without rib (SSWR), the property, the design methodand the test result of SSWR with variable thickness section and the key constructionpoints of the SSWR making good use of characteristic of hypcrbolic parabolioid shellhave been introduced in this paper. Thc applications of the SSWR in the middle andsmall-sized workshop, in the large-scale or middle-sized public buildings and in thecountryside housing of the east part of the North-West in China are also introducedthrough engincering examples, in which they all achieve great success and economic ben-efits.
