TL;DR: In this article, an original methodology for the rapid assessment of building damage caused by an excavation is presented, which combines Ground-work Impact (GI), in terms of induced greenfield displacements, and the Building Vulnerability (BV) form the basis for the GIBV damage assessment method.

TL;DR: In this article, a finite difference method was used to represent curved deep beams and the results were compared with other methods to check the accuracy of the developed analysis, the average percentages of difference for deflections and moments are (5.3%), and (7.3%) respectively which indicate the efficiency of the adopted method for analysis.
Abstract: This research deals with the linear elastic behavior of curved deep beams resting on elastic foundations with both compressional and frictional resistances. Timoshenko’s deep beam theory is extended to include the effect of curvature and the externally distributed moments under static conditions. As an application to the distributed moment generations, the problems of deep beams resting on elastic foundations with both compressional and frictional restraints have been investigated in detail. The finite difference method was used to represent curved deep beams and the results were compared with other methods to check the accuracy of the developed analysis. Several important parameters are incorporated in the analysis, namely, the vertical subgrade reaction, horizontal subgrade reaction, beam width, and also the effect of beam thickness to radius ratio on the deflections, bending moments and shear forces. The computer program (CDBFDA) (Curved Deep Beam Finite Difference Analysis Program) coded in fortran-77 for the analysis of curved deep beams on elastic foundations was formed. The results from this method are compared with other methods exact and numerical and check the accuracy of the solutions. Good agreements are found, the average percentages of difference for deflections and moments are (5.3%), and (7.3%), respectively which indicate the efficiency of the adopted method for analysis.

TL;DR: In this paper, a robust and economical shoring scheme is suggested to cater for minimal damage to the nearby buildings, based on this study, a robust as well as economical Shoring Scheme is suggested.
Abstract: Excessive settlement occurred during the installation of collection chamber of sewage pumping station induced minor-to-major damages in the adjacent structures which cautioned the authorities. CSIR-Central Building Research Institute, India, investigated and identified the cause and control further damages to the adjacent structures due to excavation construction. Initial study revealed that excessive settlement occurred due to dewatering carried out after the installation of collection chamber by well sinking method. The presence of soft soil and high water table caused soil movement towards the collection chamber, leading to severe settlement issues. This necessitated a proper study before carrying out further excavation of the adjacent inlet and screen chambers. The evaluations for the remaining two chambers have been carried out using numerical analysis by finite element method and supplemented by comparing with existing analytical approaches and field values. Based on this study, a robust as well as economical shoring scheme is suggested to cater for minimal damage to the nearby buildings.
