In this second part, archetypical steel moment frames with masonry infills are evaluated using the ATC-63 methodology, which is a systematic procedure for the determination of seismic design factors of structural systems. The ATC-63 methodology is briefly reviewed. Procedures in the ATC-63 methodology are specialized for application to infilled steel moment frames. Results from the ATC-63 evaluation of the archetypical infilled steel moment frames are presented, and are used to propose seismic design factors and design guidelines for steel moment frames with masonry infills. The applicability of the proposed seismic design factors and guidelines for reinforced concrete infilled frames is discussed.

The idea of strengthening the existing masonry infill walls of reinforced concrete (RC) frames has attracted many research groups in the last decade. The use of carbon fiber reinforced polymer (CFRP) strips along the diagonals of infills has become one major technique applied for this purpose. An experimental study conducted by the authors focused on the effect of aspect (height/width) ratio of hollow clay tile infills on the overall response attained by this strengthening methodology. Two different aspect ratios (HCT) were selected in the experimental study. However, a wider range of aspect ratios should also be investigated for design purposes. Therefore, a numerical model of the test frames are developed, which are validated by the experimental response curves. The basics of the numerical model that leads to a parametric study is the subject of this article.
