“…In Model WC1, the first cracks in the wood panel occurred in the North and South side of the column face at around 35 cm away from the top of the column. The cracks are indicated by the principal shear stress in the wood that was higher than the tangential shear strength of the wood suggested by Calderoni [10]. It was average 7.44 MPa at the location where the wood panel of the column was assembled together by using wood glue, as seen in Figure 13.…”

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.

“…Este comportamiento fue demostrado por Calderoni (Calderoni et al, 2006) en los ensayos realizados a piezas pequeñas libres de defectos, procedentes de vigas antiguas de madera. En ellos se puede observar como todas curvas de las piezas ensayadas, independientemente del origen, tienen un comportamiento muy similar en su fase elástica, pero no cuando son cargadas desde esta fase hasta la rotura.…”

This paper explores the behavior ofwooden beams tested to bending up to fracture, and later repaired with bidirectional carbon fiber fabric of two grammage types, placed in one or two layers. In addition, beams reinforced with the same fabrics were tested to flexura! strength until fracture in arder to compare the results. Far this purpose, 21 beams were tested to bending at 3 and 4 points; 13 of these beams did not have any reinforcement, 8 of them were repaired with carbon fiber reinforced polymer (CFRP) and later tested, and the other 8 beams were reinforced but were not submitted to any previous test. Results show that when the appropriate fabric strength, the repaired beams -previously collapsed-support higher loads than those that initially caused them to fracture.
