Researchers awarded a considerable attention to progressive collapse analysis in recent years avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established base deal with such catastrophic failure. For multi-story building, these proposed column removal scenario which one more columns different locations should be removed from structure. Then, re...

setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. this paper addresses multistory reinforced concrete (rc) frame buildings, regular and irregular in elevation. several multistory reinforced concrete moment resisting frames (rcmrfs) with different types of setbacks, as well as the regular frames in elevation, are designed according...

Frame theory is often credited with "bringing ideas back in" social movement studies, but frames are not the only useful ideational concepts. The older, more politicized concept of ideology needs to be used in its own right and not recast as a frame. Frame theory is rooted in linguistic studies of interaction, and points to the way shared assumptions and meanings shape the interpretation of eve...

Frame theory is often credited with “bringing ideas back in” to the study of social movements, but frames are not the only useful ideational concepts. In particular, the older, more politicized concept of ideology needs to be used in its own right and not recast as a frame. Frame theory is rooted in linguistic studies of interaction, and points to the way shared assumptions and meanings shape t...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

According to current design practices of steel moment-resisting frames, formation plastic hinges is unavoidable when the frames are supported by conventional column base systems, i.e., exposed-type and embedded-type due unequalized flexural moment demand on top first story columns [1]. Kimura et.al [3] has proposed mid-story pin system avoid from yielding realize beam-yielding mechanism applyin...

Mid-story pin column system has been proposed to realize beam yielding mechanism of a steel moment-resisting frame. In this system, connection is applied inbetween the upper and lower RC extended from base control moment demands on both ends first story column. An exposed-type adopted as connected by single anchor bolt. Static cyclic horizontal loading tests partial frame consisting second floo...

The present study investigates the seismic performance of twelve-story RC buildings focusing on structural effects flat walls which are commonly neglected in design practice. Two-span moment-resisting frame was numerically modeled considering three analytical cases: Case 0 beam-column subassembly, 1 with conventional walls, and 2 damage control were proposed authors’ previous study. Comparing m...
