Abstract Purpose Sincethe availability of natural aggregates is very sparse, recycled industrial and construction waste provides a sustainable alternative to ground improvement using vibro replacement method. Utilizing building caters the requirement for its disposal offers an effective remedy scarcity resources. The aim this study was give as material stone column. Materials methods A good column should be hard, dense, chemically inert must comply with size requirement. utilization debris...

The selection of an adequate response reduction factor (R) in the seismic design a reinforced concrete building is critical to building’s response. To construct robust structure, R should be chosen based on resilience performance. Since no background was provided for factors, study focuses right factors relation functionality, performance level, and resilience. In this study, high-rise with multiple (R = 3, 4, 5, 6) developed. Five potential recovery paths (RP-1 RP-5) that matched realistic...
