Abstract

This paper presents the possibility of using optical measuring system ARAMIS for reinforced concrete beams behaviour studies. Measurements of spatial deformations (horizontal displacements and rotation of the cross section) and cracking process (width and number of cracks) of these elements were taken into account. Such measurements are very difficult to do with the use of traditional methods. System specification has been prepared in order to, test a large area of reinforced concrete beams. It was possible among other things, to use of two sensors/two sets of cameras. Due to this fact and the unusual use for testing of reinforced concrete elements, it was necessary to develop a procedure for reinforced concrete elements measuring. To evaluate the accuracy of measurement, uncertainty of the measurement system was calculated for the configuration used in the studies. The analysis of crack formation and corresponding displacements was based on results of tests performed on 14 single-span reinforced concrete beams monotonically loaded until failure. During studies all data were collected using optical measuring system based on ARAMIS software. On the basis of research and analysis it was demonstrated that the asymmetrical distribution of rebar in reinforced concrete beam section affects on horizontal displacements and the process of crack formation on the surface of the beam.
光学测量系统在钢筋混凝土梁分析中的应用
本文介绍了利用光学测量系统ARAMIS进行钢筋混凝土梁性能研究的可能性。考虑了这些单元的空间变形(横截面的水平位移和旋转)和裂缝过程(裂缝的宽度和数量)的测量。用传统方法很难进行这样的测量。为了对大面积钢筋混凝土梁进行试验,编制了系统规范。除其他外,还可以使用两个传感器/两套照相机。由于这一事实和钢筋混凝土构件测试的不寻常用途,有必要制定一套钢筋混凝土构件测量程序。为了评估测量的准确性,对研究中使用的配置计算了测量系统的不确定度。裂缝的形成和相应的位移分析是基于对14根单跨钢筋混凝土梁进行单调加载直至破坏的试验结果。研究期间,所有数据均采用基于ARAMIS软件的光学测量系统采集。在研究分析的基础上,论证了钢筋混凝土梁截面中钢筋的不对称分布对梁的水平位移和梁表面裂缝形成过程的影响。
