“…It is highly essential the soil frequency must be greater than resonant frequencies. As per SEVENSK standard (SS-ISO 10137-2008): This Swedish standard prescribes the perception levels of human response of the HRB dwellers Farouk Mohamed I, 2016 [25], Halle brand Erik et al, 2016 [26].There is noticeable impact of displacements, speeding up, and resulting forces that restricts the comfort of residents in HRB's. There are four the effects on heel drop and walking activities such as Imperceptible, Slightly perceptible, distinctly perceptible and strongly perceptible depending upon thresholds damping ratios are as follows, Table 2:…”

The vertical growth of multi storied buildings has become requisite considering limitations on housing area and upsurge in population growth. Cities with population density >10000 person/Km2may go for high rise buildings. Multiple cases of foundation failure have been observed around the globe due to incompetent soil, weak foundation, poor building materials, faulty workmanship, excess superimposed loading, want of geotechnical investigations, and failure analysis. The analysis and design of multistoried buildings [minimum G +3]is of demand in urban and economically sound areas. The STAAD. Pro is an efficient tool adhering to IS specifications for design of structures by limit state design to avoid erroneous computations, cumbersome and time consuming processes of manual calculation in India. The software is user interface to visualize, analyze and design structures by radical finite element technique and has dynamic analysis abilities. The present work is a 3-D RCC frame having 4 bays x5m along x-direction and 3 bays x5m in z- direction were taken where each floor has 299 beams and 40umns at different elevations in each floor subjected to dead, live , wind and seismic loads as per Indian beneath different load arrangements, considering structural safety under minimum requirements. The perception levels against vibrations and different foundations against failure (especially pile foundation) is stressed for a safe, comfortable multi storied building in Indian soil.

A three-dimensional (3D) CFD model was developed, covering a square area of 3.64 km2 and comprising the Holy Mosque near its center, the actual terrain, and the main surrounding buildings. The gust wind effects on the existing cranes and the collapsed tower crane in 2015, the comfort of the pedestrians, and the air quality were studied for the first time in this area. The air quality was related to calm speed, accelerating the spreading of infectious diseases. The wind comfort levels were achieved in all selected locations. The wind speeds are generally low in the area. However, gusting wind currents appeared from limited directions, causing increments in wind speeds up to 30% and causing the tower crane to collapse. Therefore, finalizing work on some cranes is recommended soon, lowering the crane boom and stopping working on windy days or changing their places. The air quality in some sites may be relatively poor, such as at the lower terraces level. New tall buildings surrounding the mosque from the north and the east are not recommended unless studying their impacts on the air quality. Pruning north and east mounts can remarkably improve natural ventilation. Large-scale fans are another solution after a detailed simulation study.

A CFD model was developed, covering a square area of 3.64 km2 and comprising the Holy Mosque near its center, the actual terrain, and the main buildings surrounding the Mosque. The gust wind effects on the existing cranes, the comfort of the pedestrians, and the air quality were studied for the first time in this Holy area. The air quality in this study was related to calm speed and creating a fertile environment for spreading infectious diseases. The study revealed that wind comfort levels are achieved in nearly all selected locations. Also, the wind speeds are generally low in the area. However, gusting wind currents appeared from limited directions, causing more wind loads on cranes. It is recommended to finalize some cranes' work shortly in specific locations or change their places, lower the crane boom at rest, and stop working on windy days. The air quality in some locations may be considered relatively poor. New tall buildings surrounding the Holy Mosque from the North and the East are not recommended except after studying their impacts on the air quality. Pruning North and/or East Mounts can remarkably improve natural ventilation. Large-scale fans are a solution after detailed study and simulation.
