Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

Accurate modeling of masonry has been a major concern of the researchers in the past decades. Besides reinforced and unreinforced masonry structures, masonry can be found in frame structures as infill panels which are used as partitions and/or external walls. These elements role as a part of structure and introduce a large degree of nonlinearity into the system. In this study, a micro-modeling ...

This paper investigated progressive collapse analysis of three-dimensional (3D) reinforced concrete (RC) frames that are optimized for carrying structural loads by introducing a unique simultaneous multi-column removal load path using Machine Learning. The investigation includes formulating an integrated computational framework incorporates self-training machine learning algorithm. algorithm is...

The optimum structural design of real-world 3D concrete building frames to modern standards is a complex and computationally expensive task. Hence, the use surrogate-based optimization (SBO) methodologies must be investigated reduce computational cost. present study applies, for first time, fully-fledged SBO algorithm frames. More particularly, applied minimum material cost 4-storey 12-storey R...

Currently, ordinary concrete and steel bars are mostly used in frames, but there is no systematic research on the impact of high toughness low yield point seismic performance frames. The low-cycle repeated load test three 1/3 ratio two-story two-span cast-in-situ frame specimens carried out. resilience model hysteresis characteristics, displacement ductility, energy dissipation capacity studied...

The present study evaluates the utilization of shotcrete sandwich panel (SSP) infill and CFRP strips to strengthen reinforced concrete (RC) frames. To this end, a diagonal strip-infilled RC frame, an SSP-infilled control specimen (a bare frame) were examined as single-story specimens in terms in-plane seismic response. This work compared stiffness degradation, damping, cyclic lateral Also, avai...
