Abstract
So far, numerous numerical studies have been conducted on the behaviour of Composite Reinforced Concrete-Steel (RCS) beam-to-column connections. However, the lack of studies regarding the steel joist-concrete girder connection has yet to be addressed through comprehensive finite element methods to get an understanding of the influential parameters. Hence, in this paper, composite connection of embedded steel joist in concrete girder is investigated with appropriate finite element software, namely, ABAQUS. The validity of the proposed model is examined by the comparison made with the test data presented in reference studies. Results indicate that maximum bending capacity of the connection is achieved when embedment ratio is 1.78. Moreover, double web angles in the embedment region significantly reduce the embedment length required to achieve the maximum bending capacity. Finally, damage analyses show that bending capacity of the concrete girder is slightly reduced in the connection zone.

Abstract
The paper aimed to present the different ways of determining the cracks. Cracks are the lines on the surface of something along which it has split without breaking apart. There are many ways we can determine like with the help of strain gauge, DMI technology, etc. In this review, an effort has been made to find out the various methods by which we can find the cause and location of the cracks. In this review, various methods, technologies, sensors’ articles are reviewed and on the basis of that study has been done. This study has been done. This study helps the civil engineers and researchers to find out the location and cause of cracks.
