Infilled frames: developments in the evaluation of the stiffening effect of infills

Structural Engineering and Mechanics, 2003
In order to consider the modified seismic response of framed structures in the presence of masonry infills, proper models have to be formulated. Because of the complexity of the problem, a careful definition of a diagonal pin-jointed strut, able to represent the horizontal force-interstorey displacement cyclic law of the actual infill, may be a ...

Designing infilled reinforced concrete frames with the ‘strong frame-weak infill’ principle

Engineering Structures, 2016
Abstract This paper presents an experimental study of the seismic performance of a category of reinforced concrete (RC) frame with weak infill panel and the complicated interaction between bounding frame and infill panel at different loading stages. Large-scale infilled RC frame specimens, which were fabricated to simulate those in as-built RC frame ...

Unified Plastic Analysis for Infilled Frames

Journal of Structural Engineering, 1985
Based on tests and nonlinear finite element analyses, a unified plastic analysis for infilled frames with three types of interface conditions is proposed, in which the stress redistribution towards collapse and the conditions at the infill‐frame interface are taken into account.

A MULTISCALE APPROACH FOR MODELING OF INFILLED FRAMES

Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015
The behavior of existing reinforced concrete buildings towards to the seismic actions is strongly affected by the infill walls. Although they assume an important role in the global response of the buildings, modeling of infilled frames is quite complex as a result of the many variables involved. These factors (such as the various constructive solutions;

Hysteretic Response of Reinforced‐Concrete Infilled Frames

Journal of Structural Engineering, 1992
Strengthening of framed reinforced concrete structures by cast‐in‐place reinforced concrete infills is commonly used in practice. The objective of this study is to investigate the behavior of such infilled frames under seismic loads. For this purpose, 14 two‐story, one‐bay infilled frames are tested under reversed cyclic loading simulating seismic ...
