【摘要】：本試驗(yàn)首先進(jìn)行了廢玻璃鋼筋混凝土簡(jiǎn)支梁試驗(yàn)的設(shè)計(jì)與試件安裝。隨后開展了廢玻璃混凝土梁在不同剪跨比下的斜截面抗剪試驗(yàn)研究,其研究過程主要是針對(duì)抗剪受力機(jī)理進(jìn)行理論分析,對(duì)其破壞形態(tài)進(jìn)行理性討論;對(duì)斜截面的各個(gè)破壞著力點(diǎn)進(jìn)行荷載聯(lián)立分析探討;最后通過分析各國的規(guī)范公式計(jì)算推導(dǎo)廢玻璃混凝土梁的抗剪承載力適用性并擬合分析折減出斜截面最大裂縫寬度計(jì)算公式。其試驗(yàn)所取得成果如下:(1)通過試驗(yàn)研究,發(fā)現(xiàn)廢玻璃混凝土與普通混凝土有著相似的力學(xué)性能,但廢玻璃替代部分骨料混凝土的立方體抗壓強(qiáng)度較同條件普通混凝土低。(2)廢玻璃粗骨料鋼筋混凝土梁的抗剪承載力低于普通鋼筋混凝土梁與廢玻璃細(xì)骨料鋼筋混凝土梁。(3)分析了廢玻璃混凝土梁撓度變形,得出斜壓破壞下廢玻璃細(xì)骨料混凝土梁的撓度變化規(guī)律、剪壓破壞下的廢玻璃細(xì)骨料混凝土梁與普通混凝土梁荷載-撓度曲線、斜拉破壞之下廢玻璃細(xì)骨料混凝土梁與廢玻璃粗骨料混凝土梁的撓度曲線。(4)通過分析對(duì)比探討廢玻璃混凝土梁抗剪承載力公式,認(rèn)為六種規(guī)范公式普通混凝土梁與廢玻璃細(xì)骨料混凝土梁的值誤差比較接近,其抗剪能力也趨近相同,但廢玻璃粗骨料混凝土梁的計(jì)算與實(shí)測(cè)值走向不明晰,偏差較大。
[Abstract]:The first test was carried out with the specimen installation design of waste glass reinforced concrete beam test. Then carry out waste glass concrete beams with different shear span ratio under oblique section shear test, the study is mainly aimed at the shear mechanism of theoretical analysis, rational discussion of the failure pattern of each; the inclined section of the focal point for the analysis of failure load simultaneous finally by standard formula; analysis of the calculation of waste glass shear strength of reinforced concrete beams and the applicability of the fitting analysis of reduction the maximum crack width of diagonal section calculation formula. The experimental results are as follows: (1) through the experimental research, found that waste glass concrete and ordinary concrete has similar mechanical properties, compressive strength but instead of part of waste glass aggregate concrete compared with ordinary concrete conditions. (2) low waste glass aggregate The shear capacity is lower than that of ordinary reinforced concrete beams and waste glass aggregate reinforced concrete beams of reinforced concrete beams. (3) the deformation of waste glass concrete beams is analyzed, the baroclinic destruction of waste glass deflection of fine aggregate concrete beams, shear compression failure of waste glass of fine aggregate concrete and ordinary concrete beam beam load deflection curve, diagonal tension failure under the deflection curve of waste glass fine aggregate concrete beams and waste glass aggregate concrete beams. (4) through the analysis and comparison of waste glass in concrete beam shear capacity formula, that six kinds of standard formula of common concrete beam and waste glass of fine aggregate concrete beams is close to the value of error, the shear capacity is approaching the same, but the calculation and measurement of waste glass aggregate concrete beams to value is not clear, large deviations.
