“…It is found that convergence is difficult to achieve using the default values due to the associated large deflections and the highly nonlinear behavior of the concrete elements. Thus, in order to obtain convergence of the equilibrium iterations, the convergence tolerance limits are increased to 15% for the displacement checking criterion [9].…”

ABSTRACT:A new hybrid structural column system called Engineering Wood Encased Concrete-Steel (EWECS) column was developed for low and high seismic zones. Experimental studies on the seismic behavior of EWECS columns with varying shear span to depth ratio (shear-span ratio) have been conducted by one of the authors. To complement and validate the experimental program, finite element analysis (FEA) on EWECS columns with varying shear-span ratio ranging 1.0 to 2.0 under constant axial and lateral cyclic loads are summarized. This numerical analysis uses finite element program, ANSYS APDL v.14, to investigate the structural performance of the EWECS columns, which was compared with the experimental results. A detailed three-dimensional (3D) nonlinear FE model of three EWECS columns with varying shearspan ratio, subjected constant axial and lateral cyclic loads are performed. The FEA results showed that the shear-span ratio affected by the maximum shear strength and failure mode of the EWECS columns. The maximum strength of the columns increased with decreasing shear-span ratio. The stress distribution on the FE models represented the failure mode of the EWECS columns well. More damages on the columns were observed with decreasing shear-span ratio. In general, good agreement between the experimental data and the FE models output in terms of the seismic performance and failure mode was observed.

The objective of a present work is to compare an experimental and analytical study on precast frame. A precast frame development includes the whole structural components being manufactured off-site. Connection is the crucial part in precast frame because it influences the performance of structural behavior. There are various connections in the beam -column, out of which grout connection are chosen in this study. A scale model is created for the identified critical bay. A precast frame are constructed and tested under loading condition. The parameters considered for the present study are Ultimate Load Carrying Capacity, Cracking Pattern and Failure Mode, Load Displacement behavior and Energy Dissipation Capacity. The analytical study of the precast frame which are done by ANSYS software. After analyzing a frame in Ansys, both experimental and analytical works are compared in this paper.

Abstract. The numerical behaviour of steel fibre reinforced concrete (SFRC) corbels reinforced with different fibre volume ratio subjected to vertical incremental load is presented in this paper. Precast concrete structures had become popular in the construction field, which offer a faster, neater, safer, easier and cheaper construction work. The construction components are prefabricated in controlled environment under strict supervision before being erected on site. However, precast beam-column connections are prone to failure due to the brittle properties of concrete. Finite element analysis (FEA) is adopted due to the nonlinear behaviour of concrete and SFRC. The key objective of this research is to develop a reliable nonlinear FEA model to represent the behaviour of reinforced concrete corbel. The developed model is validated with experimental data from previous researches. Then, the validated FEA model is used to predict the behaviour of SFRC corbel reinforced with different fibre volume ratio by changing the material parameters. The results show that the addition of steel fibre (SF) increases the load carrying capacity, ductility, stiffness, and changed the failure mode of corbel from brittle bending-shear to flexural ductile. On the other hand, the increasing of SF volume ratio also leads to increased load carrying capacity, ductility, and stiffness of corbel.
