As a new type structure, there were no reports and literature of the relevant studies on prestressed space composite trass at present.

本課題研究的預(yù)應(yīng)力空間組合結(jié)構(gòu)是一種新型結(jié)構(gòu)操美屄不卡黄色网站，目前還沒有相關(guān)的研究和文獻報導(dǎo)。

Based on screening and sampling, properties of trass and trass concrete in Ximeng area of Inner Mongolia was studied.

通過篩分選樣人人插人人做，對內(nèi)蒙古錫盟地區(qū)大量蘊藏的火山渣及火山渣混凝土進行了材料性能實驗研究爱爱免费网站欧美。

The results showed that the trass in this area is feasible as a kind of more ideal natural lightweight aggregate, and the trass concrete can reach the grade of intensity the structure component needs.

結(jié)果表明，該地區(qū)的火山渣作為一種比較理想的天然輕骨料是可行的日韩侵犯精品视频在线，用此火山渣配置的火山渣混凝土能夠達到結(jié)構(gòu)構(gòu)件需要的強度等級日本免费一级高清婬片日本。

The research is to develop a new material----high performance concrete of hill sand on the basis of practice of high strength concrete of hill sand and knowledge of ultra-fine trass additive by using concrete material in Guizhou and mixing fly ash.

本文通過對配制的山砂高性能混凝土和普通混凝土的拌合物性能、力學(xué)性能超碰a、長期性能及耐久性能的研究一区二区黄色大片，得到流動性、保水性女人16一毛片、粘聚性等性能優(yōu)良的山砂高性能混凝土日韩欧美中文国产。

This paper mainly focused on some basic research as follows:(1) ANSYS finite element calculation software and the APDL design language were used to set up two model structures—the reinforced concrete floor model and the prestressed space composite trass model.

本文就該結(jié)構(gòu)做了以下幾點基礎(chǔ)性研究工作：(1)利用ANSYS有限元分析軟件和APDL參數(shù)設(shè)計語言建立了兩個模型：鋼筋混凝土樓板模型和預(yù)應(yīng)力空間組合結(jié)構(gòu)模型，對樓板模型和預(yù)應(yīng)力空間組合結(jié)構(gòu)模型分別進行了非線性靜力分析国产老女人操逼视频，模態(tài)分析和豎向動力荷載下的非線性瞬態(tài)分析AAA无码精品，并對兩種結(jié)構(gòu)的力學(xué)行為做了比較，得到了一些初步結(jié)論黄色国产一级片浪潮骚货。
