Abstract

This study aims to investigate the shear behavior and resistance of brick walls produced by various knitting types. For this purpose, 15 samples were produced using Holland knitting, block knitting, cross knitting, lock knitting, and plain knitting. The samples were forced in experiments to collapse and in the non-linear region, the changes in the samples related with shear forces and shear rigidity of the wall sections were determined. In the performed experimental study, the standard sliding resistance test technique for the masonry wall samples has been determined as recommended in ASTM Standard 1391-81. The numerical modeling was carried out by the finite elements method with the program package Ansys, taking into account the local mechanical parameters of bricks and mortar. The behavior of the experimental samples and the cracks occurred during the experiments were analyzed and shear stress graphs and load-displacement graphs were derived. The modeling with the Ansys program was compared with the experimental results and the most appropriate wall knitting type could be proposed.

Kurzfassung

Die dem vorliegenden Beitrag zugrunde liegende Studie hatte das Ziel, das Scherverhalten und den Widerstand von nach verschiedenen Mustern gemauerten Wänden zu untersuchen. Zu diesem Zweck wurden 15 Proben mit verschiedenen Mauerstrukturen hergestellt. Diese Proben wurden in Experimenten zum Kollabieren gebracht und im nicht-linearen Bereich wurden die Veränderungen bezüglich der Scherkräfte und des Scherwiderstandes der Wandsektionen bestimmt. In der experimentellen Studie wurde die Standardgleitversuchstechnik angewendet, wie sie im ASTM Standard 1391-81 empfohlen wird. Die numerischen Simulationen wurden mit dem Programmpaket Ansys ausgeführt, wobei die lokalen mechanischen Parameter der Mauersteine und des Mörtels einbezogen wurden. Das Verhalten der Proben und das Auftreten von Rissen in den Experimenten wurde analysiert und es wurden Graphen der Schubspannung und Last-Verschiebungs-Diagramme abgeleitet. Die Resultate der Modellierungen mit dem Ansys-Programm wurden mit den experimentellen Ergebnissen verglichen und daraus die am besten geignete Mauerstruktur abgeleitet.
