摘要
本研究的重点是在地震情况下开发大型( 32毫米)树脂粘结混凝土后安装锚的表征系统。它是基于ACI 355.411要求的试验及其条件，提出一个新的试验和试验设计，满足这些要求，因为在标准中提出的设计使试验不可行。对开裂混凝土(裂缝宽度为0.3 mm)、地震拉伸(裂缝宽度为0.5 mm +加载循环)和地震剪切(裂缝宽度为0.5 mm +加载循环)进行了拉伸特性试验，获得了降低阻力混凝土的保证值(95%百分位数)。PALABRAS CLAVE:踝骨，树脂，hormigón, sismo, tracción, cortante。
Caracterización experimental de anclajes post instalados de gran capacidad en situaciones sísmicas
This research focuses on the development of a characterization system for large (32 mm), resin-bonded post-installed anchors in concrete in case of an earthquake. It is based on the tests required by ACI 355.411 and its conditions, proposing a new test and test design that meets these since the design proposed in the standard makes the test unfeasible. Tensile characterization tests are carried out on cracked concrete (0.3 mm crack opening), seismic tension (0.5 mm crack opening plus loading cycles) and seismic shear (0.5 mm crack opening plus loading cycles) obtaining guaranteed values (95% percentile) for reduced resistance concretes. PALABRAS CLAVE: anclaje, resina, hormigón, sismo, tracción, cortante.
