The equations are developed on the basis of both cyclic and monotonic experiments of an extensive database compiled by the author Appendix A.

MUROS – What does MUROS stand for? The Free Dictionary

Confinaca developing the empirical equation for ultimate deformation capacity of C M walls, tie column transverse reinforcement proved insignificant to the model. However, for the experiments that are only supplemented with the mean recorded response, result parameters are only presented in terms of their average values.

Therefore, both dynamic testing of specimens having almost identical characteristics to typical C M walls and in-situ testing of C M walls are needed for validation of the models under dynamic loading conditions, and for adjustment appropriate in building practice.

This discrepancy may be related to the number of ceramic specimens available to develop the model, and therefore, more experimental tests of Mamposterai M walls made of these units may be required. As is apparent from this figure, in spite of being very similar in its formulation to the empirical model of this study, TK97 overestimates the contribution of tie columns by over three times. Key parameters that best describe the characteristics conrinada the masonry panels are presented in Table A-2 in terms of notations, remarks, units, and their definitions.

Xonfinada support undoubtedly contributed to the quality of this work. Therefore, panel aspect ratio appears insignificant for squat C M walls with aspect rations close to one.

When extensively damaged masonry panels are replaced, these connection rebar can be effectively utilized to interconnect the newly-constructed panel with its confining elements Yoshmiura and Kikuchi, Result parameters have been measured for both positive and negative directions, and then the averages added as indicators of the overall seismic performance.

However, based on the results of experimental tests, the effect of panel horizontal reinforcement on the elastic characteristics of C M walls is almost negligible Yoshimura et al, ; Mampposteria and Meli, ; Aguilar, ; Liba et al, ; Alcocer and Zepeda, Summary and future research 77 4. The masonry panel, in turn, would be under the effect of more compressive stresses, provided that an mamposterka bond allows sufficient load transfer between wall and confining elements.

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. Tie columns should be provided with sufficient longitudinal reinforcement to avoid the predominance of flexural deformations and wall uplift as a result of rebar yielding at the base of columns 13 Chapter 2: Chapter – 7 Flores, L.

However, the results of experimental tests by Alcocer and Zepeda indicate that the seismic resistance of C M walls made of these brick units may be only accounted for i f provided with minimum panel reinforcement and external tie columns 10 Chapter 2: At this stage, as experimental results indicate, strain in tie-column longitudinal reinforcement changes alternately from 6 Chapter 2: Performance-based seismic models for confined masonry wall further limited by being developed only for “typical” C M walls.

The democratic meaning of the wall in Rogelio Salmona’s work: Such plots, in fact, only reveal trends when all variables other than the mamposteri of interest are kept nearly constant.

It is worth noting that such low reinforcement ratios, however, are not common in practice. These predictive equations are either highly influenced by the formulas originally developed for unreinforced and reinforced masonry RM walls or are only created on the basis of a limited number of experiments e.

Table A-7 documents the range, mean and coefficient of variation for the chief variables that best define the characteristics of bond beams. Therefore, column transverse reinforcement was excluded from the final model Equation The expected ductility factors for different unit materials are presented in Table A “Behaviour of multi-perforated clay brick walls under earthquake-type loading.

Tie column characteristics 90 Table A Although the stipulated code values vary slightly depending on the region they are developed for, almost all codes Eurocode 8, ; INN, ; N T C – M; NSR, call for the minimum transverse reinforcement of 6 mm hoops at to mm respectively. Lack of distinct relationship between fi and p hc-fyhc 58 Figure The proposed backbone model is found to simulate reasonably well the seismic behaviour of C M walls whose properties conform to the assumptions of the model.
