Fragility Curves of Regular and Irregular Moment-Resisting

WebRecent developments in engineered timber products, and their availability, durability, and renewability, have led to taller and more flexible buildings. However, these buildings may experience excessive vibrations, resulting in safety and serviceability issues due to wind or earthquake loads. This paper presents a dynamic analysis of a 42-story-tall hybrid-timber … WebThe story drift is calculated between the floors. The relative movement of the two different stories (movement of one floor compared to other) is checked. As we discussed story drift is the relative movement of the floor … WebSince the inter-story drift ratio can be used to quantify P-Delta effects, it is necessary to analyze the maximum inter-story drift ratio (MIDR) demands. Figure 6 and Figure 7 show the MIDR demands of the three structures under the 40 … family fare greenville nc
