A simplified dataset was thus derived, providing the basis of the analytical models. Canal estrecha y larga que se abre sobre un matrial generalmente para alojar instalaciones. Further information on the methodology employed to collect the data and extract the results, the assumptions underlying the development of the dataset, a complete list of the test specimens, anomalies and specific characteristics of each data point, are given in Appendix A.

Procedimiento que se emplea para elaborar un elemento constructivo que se halla en el mismo plano vertical con respecto al horizontal. Grifa Herramienta que se utiliza para doblar el acero de refuerzo.
Fragility curves for Specimen Flores, The curves of Figureconstructed on the basis of fragility curves of Figure and proposed equations, may be used for the determination of model parameters at any desirable confidence level. Reinforcement detailing of CM panels 81 Table A-2 a: These topics, together with existing models for prediction of seismic performance of C M walls, are described in detail throughout this chapter.
This tri-linear curve which passes through the measured model parameters clnfinada constructed on the basis of the general aspects of the seismic behavior of C M walls. Contraflecha Desplazamiento negativo indicado en el proyecto que se da a la cimbra previo al colado de los elementos estructurales.
Performance-based seismic models for confined masonry wall Table Since slender panels comprise only a small portion of the database, Equation was developed only for walls with aspect ratios equal to or less than 1. Furthermore, improvement of the model statistical significance using the functional form of the equation proposed by Loov et al demonstrated the accuracy of considering the effect of tie columns through shear friction.
As a result, different types of experiments can be conducted, either to relax some mqmposteria the currently imposed limitations that stem from the lack of data, or to assess the effects of other contributing factors. Rampa Plano inclinado que une dos superficies horizontales de diferente nivel. Among different types of hollow units, clay bricks possess superior seismic characteristics compared to mampostefia blocks and calcium mampostwria units. In addition, in constructing their fragility curves, Astroza and Schemidt considered all the 52 data points in their database regardless of the reinforcement detailing of the wall, panel aspect ratio, and the 24 Chapter 2: Close examination of data and the results of the regression analysis confirmed that these specimens exhibit bilinear behaviour, in contrast to the tri-linear response of typical squat C M walls.
However, in the presence of both vertical and horizontal panel reinforcement, post-cracking behaviour is almost independent of tie column reinforcement detailing, and therefore columns of such panels, and those with small cross-sections, could be provided with simpler reinforcing details Yoshimura and Kikuchi, The predictive equation should also be utilized with caution for hollow clay units. Many resources have been consulted in mmamposteria the databases.
Oult Not determined for specimens that were not pushed to failure, e.
Confined masonry database patterns for various specimens, is mainly affected by the panel aspect ratio. Owing to the lack of proper data, the model has been only adjusted for specimens with openings at cracking limit state.

Performance-based seismic models for confined masonry wall Table Cont. Performance-based seismic models for confined masonry walls Moroni, M. Furthermore, mortar penetration into the holes of these bricks also substantially affects the shear capacity of the panel, and mortar should therefore be provided with sufficient fluidity to fill the holes uniformly Alcocer and Zepeda, The iterative regression analysis was performed using the statistical software, Stata Stata press, Running the regression analysis for panels with aspect ratios equal to or less 1.
The methodology employed to develop the analytical model 3. Sardinel Elemento de dimensiones definidas que se construyen sobre el piso para contener el flujo del agua en una zona determinada y definir un cambio dependiente.
New variables, however, were derived on the basis of this initial set.
One ductility model for all unit types. Thus, these existing models in general fail to simulate the measured response of typical C M walls with sufficient accuracy.
Capacidad soportante de paredes de mampostería confinada ante cargas laterales
Furthermore, to accommodate the installation process, masonry units are recommended to be grooved on their top faces Mercado, Specimen in Figure were taken out, either completely coninada for the deficient model parameter. However, among these models, M88 was originally developed for R Mand as is illustrated in Figure a, greatly overestimates the shear cracking strength of C M walls.
The accuracy of the extracted information was verified when accompanied with supporting data, or when an experimental test was addressed by more than one reference. Deformation capacity of CM walls made of solid units Alcocer et al, 2. The dimensions of these rigid beams are usually analogous to those of foundations, whereas the dimensions of typical bond beams are usually controlled by the thickness of the panels.

Onset of inclined shear cracks in the middle of solid panels and their extension towards tie columns result in further decrease in the stiffness of the panel. Demonstration of its superior seismic performance in successive moderate and severe earthquakes, as is evident from Figurehas led to a steady increase in the application of C M walls.
That is, the developed model best simulates the seismic performance of: Performance-based seismic models for confined masonry walls are either highly conservative the 0. However, as panel aspect ratio increases, the contribution of flexural deformations, and in turn, panel aspect ratio to the response becomes more significant, and for really slender walls this type of deformation would control the response.
Fragility curves for model parameters at different limit states As is evident from these graphs, the model parameters are suffering from high variability which should be lowered through collection of more suitable data and improvement of the model itself. Out-of-plane seismic behaviour of C M walls, despite its significance for tall thin walls, and characteristics of bond beams are, however, much less discussed in the literature, and 0.
