Based on the test data of hundreds of pre - stressed concrete beams , this paper studies the factors that influence the ultimate shear strength of those beams . and those factors have been analyzed by correlation analysis of grey system theory . the analysis result shows that which is the first factor influences the ultimate shear strength and which one is the next 本文根據(jù)國內(nèi)外預(yù)應(yīng)力混凝土梁斜截面抗剪承載力試驗(yàn)資料,分析了影響預(yù)應(yīng)力混凝土梁斜截面抗剪承載力的主要因素,并對這些因素進(jìn)行灰色關(guān)聯(lián)分析,得出各因子對預(yù)應(yīng)力混凝土梁斜截面抗剪承載力影響程度的大小排序。
The feasibility of applying neural networks to evaluate the performance of the columns is investigated . two prediction models , one for earthquake - resistance property and the other for ultimate shear strength , are established . in the further research , the influence of various parameters on the earthquake - resistance property and ultimate shear strength are discussed 探索應(yīng)用人工神經(jīng)網(wǎng)絡(luò)對核心柱的力學(xué)性能進(jìn)行評估的可能性,分別建立了核心柱的抗震性能和抗剪承載力的預(yù)測模型,進(jìn)而利用該模型討論了不同參數(shù)變化對二者的影響。
