【摘要】：隨著國家工程建設(shè)的不斷發(fā)展，各種功能和不同特點的新型模板和模板支撐體系不斷出現(xiàn)，如常見的塑料模板和數(shù)字化模板支撐系統(tǒng)等。塑料模板表面平整，重量輕，耐腐蝕性耐水性強，可塑性強，周轉(zhuǎn)次數(shù)高；數(shù)字化模板支撐體系采用高性能冷軋鋼，力學(xué)性能好，耐腐蝕度較大，，安裝拆卸方便，在工程中得到了廣泛的推廣使用。但是對新型模板的支承設(shè)計的研究沒有得到充分的重視，當(dāng)前仍然采用建筑施工模板安全技術(shù)規(guī)范中的三跨連續(xù)梁模型進(jìn)行模板的支承分析，因此本文對塑料模板在雙線性支承條件下的支承布置采用雙向受彎板模型計算分析，并編制了便于工程應(yīng)用的支承分析軟件，為支承布置分析提供了一種新的方法，并且對模板支承研究提供了一定的參考依據(jù)。 本文的研究內(nèi)容主要由以下幾個方面： （1）通過對塑料模板和數(shù)字化模板支撐體系的特點進(jìn)行研究，通過一定的假設(shè)條件，得到雙向受彎板模型下，多向線性支承條件的塑料模板的支承分析模型，為進(jìn)行數(shù)值分析研究提供基礎(chǔ)； （2）對模板的支承分析模型按照有限元分析的步驟，選取合適的分析單元類型，進(jìn)行網(wǎng)格劃分、單元分析、整體分析和求解位移內(nèi)力應(yīng)力的理論分析，得到進(jìn)行數(shù)值分析編程的基本算法表示； （3）根據(jù)數(shù)值分析的算法，采用VC語言編寫數(shù)值分析的程序函數(shù)，并根據(jù)控制條件編寫優(yōu)化命令程序； （4）利用程序函數(shù)，結(jié)合MFC應(yīng)用程序框架在VC++6.0編程環(huán)境下編制模板支承分析布置的工程軟件，對工程案例進(jìn)行軟件分析；采用有限元數(shù)值分析軟件ANSYS10.0，利用SHELL63單元，對軟件分析結(jié)果進(jìn)行數(shù)值分析，驗證軟件分析的精確性和可靠性；對兩種計算模型的計算結(jié)果進(jìn)行對比，分析雙向受彎板計算模型的特點和適用性。
[Abstract]:With the continuous development of national engineering construction, various functions and different characteristics of new formwork and formwork support system are emerging, such as common plastic template and digital template support system, etc. The plastic template has a flat surface, light weight, etc. High corrosion resistance, high plasticity, high turnover times, high performance cold rolled steel with high performance, good mechanical properties, high corrosion resistance, convenient installation and disassembly, It has been widely used in engineering. However, the research on supporting design of new formwork has not been paid enough attention to. At present, the three-span continuous beam model in the safety technical specification of building construction formwork is still used to carry out the support analysis of the formwork. In this paper, bidirectional bending plate model is used to calculate and analyze the support arrangement of plastic formwork under bilinear support condition, and a supporting analysis software is developed for engineering application, which provides a new method for the analysis of support arrangement. It also provides a certain reference for the research of formwork support. The main contents of this paper are as follows:. 1) by studying the characteristics of plastic formwork and digital formwork support system, and under certain hypothetical conditions, the support analysis model of plastic formwork with multi-direction linear supporting conditions under bidirectional bending plate model is obtained. To provide a foundation for numerical analysis; 2) according to the steps of finite element analysis, the supporting analysis model of the template is selected, the appropriate analysis element type is selected, the mesh division, the element analysis, the whole analysis and the theoretical analysis to solve the internal force and stress of displacement are carried out. The basic algorithm representation of numerical analysis programming is obtained. According to the algorithm of numerical analysis, the program function of numerical analysis is compiled by VC language, and the optimized command program is compiled according to the control condition. 4) using program function and combining with MFC application program framework in VC 6.0 programming environment to compile the engineering software of formwork support analysis arrangement, software analysis of engineering case, finite element numerical analysis software ANSYS10.0 and SHELL63 unit, Numerical analysis is carried out to verify the accuracy and reliability of the software analysis, and the characteristics and applicability of the bidirectional bending plate model are analyzed by comparing the results of the two kinds of calculation models.
