钢筋混凝土开洞梁受力性能研究
|
摘要
在高层建筑中采用开孔梁,使设备管道从梁腹中穿过,能显著降低建筑物层高,增大建筑物使用面积,可以有效地降低建筑物的造价和使用维修费用,具有良好的综合经济效益。与现在常用的结构形式相比,钢筋混凝土开孔梁具有受力性能好,材料用量省和工程造价低等特点,在工程实践中有广阔的应用前景。
本论文对钢筋混凝土梁进行了理论研究,论述了钢筋混凝土的本构关系及有限元模型。利用大型有限元软件建立了钢筋混凝土梁开圆孔和开方孔的有限元模型,并通过应力、挠度和应变三个参数的变化分析了钢筋混凝土梁开矩形孔时,孔洞尺寸及水平位置对其受力性能的影响;钢筋混凝土梁开圆孔时,孔洞的尺寸及位置对孔口应力及承载力的影响。
The use of high-rise building in Beams with Large open, so that equipment from the beam pipe through the abdomen, can significantly reduce the building height and increase the use of an area of the building, can effectively reduce the cost and use of buildings and maintenance costs, and has a good comprehensive cost-effective. And the structure now used as compared to RC Beams with Large open with good mechanical properties, materials and the amount of the province and low construction cost, engineering practice has a broad application prospects.
In this paper, reinforced concrete beam on the theoretical study on the constitutive relationship of reinforced concrete and the finite element model. The use of large-scale finite element software to establish a reinforced concrete beam hole and open hole prescribing finite element model, and through stress, deflection and strain analysis of the three parameters of the reinforced concrete beams of rectangular open-hole, the hole size and the level of location of the its impact on mechanical properties; reinforced concrete beam opening hole, the holes on the orifice size and location of the impact of stress and bearing capacity.
