where is the intensity of turbulence at height which is equivalent to 0.6h, but not less than for all building heights. h is the mean roof height. and should be considered as 3.4. The background response is given by: (11) where B is the horizontal dimension, and stands for the integral length scale of turbulence at 0.6h height. can be estimated by using the following formula: (12) where and are constants listed in Table 26.9-1 in ASCE 7-10. The parameters used to estimate gust factor are listed in Table 1. Finally, the gust factor was calculated as 0.89. In order to comprehensively evaluate the procedure defined by ASCE 7-10, new subdivisions are defined for each zone on the roof surface as can be seen in Figure 18, and …show more content…
(13) After calculating the new time history, , the peak pressure values should be evaluated. The peak pressure is a random variable with a distribution and a mean value. As a result, it is not possible to get the same value for peak pressures in different records while having the same mean value. Therefore, it is essential to estimate the probability of the peak value and refer, in the comparisons, to a specified percentage point of the distribution (Simiu 2011). To do so, in this study, the peak values are extracted from the time series at each tap locations by using the approach introduced in Ref. (Sadek and Simiu 2002). A MATLAB function for computing of quantiles (i.e., values corresponding to specified probabilities of non-exceedance) of the maximum and minimum values of the input time series was developed by NIST which is accessible on the NIST website (Main 2011). The function of “maxminqnt” is called within MATLAB as follows: [max_qnt, min_qnt] = maxminqnt (X, dur_ratio, CDF_qnt) (14) This function was used to calculate 95% peak quantile of the maximum (max_qnt) and minimum (min_qnt) values of time series of pressure coefficients. As can be seen in equation (5-28), this function requires three input arguments. The first input argument, “X”, stands for the time history of pressure data, and the second input argument “dur_ratio”, defines the ratio of the duration for which peaks are required to the

The highest peaks seen on the graphs are due to the musical intonations I am performing. This could be measured by whether I used a pedal or not, what song I was playing, and whether that song was played Legato or Staccato. Because there are so many factors to how an instrument may affect the levels. For example, on the second graph we see the levels peak at 11:30 - 11:40, times where I was playing scales; scales without any soft or smooth rhythm, but rather loud and consistent patterns. The max reached close to 85 Leq, decreasing soon after and increasing once again towards the end of the lessons where I was playing my concert pieces. These implicate when I may have been playing loud and dense melodies, such

The building is located in Orlando. I performed the following tasks for this project: (1) determined the risk category of building using Table 1.5-1 ASCE7-10, (2) determined the basic wind speed for the applicable risk category, (3) determine the wind load parameters, (4) determined the velocity pressure exposure coefficient (ASCE 7-10), (5) determined velocity pressure, (6) determined external pressure coefficient (Page 264 ASCE 7-10), (7) calculated wind pressure, and (8) determined the peak displacement at the top of the building (both along-wind and
Based on the chart, the mean was calculated by adding up the sum of the list and divide 18, which the number of the total listed prices. The mean is 135,000, which mean the average of the listed price. Secondly, the median was calculated by listing the number in numerical order from lowest to highest and located the number in the middle 126,000. The median represents the middle number of the listed price. After calculating the median I located the minimum and maximum based the lowest and highest data, which are 48,000 and 338,000. These represent the range of the listed price. Lastly, I used the formula to get the

Stability and balance is also achieved through the incorporation of the vertical and horizontal planes. In the southwest facade of the building the vertical slits are balanced with the horizontal planes created by the cubes, cornice and the ornamental horizontal band that runs halfway through the walls. These vertical and horizontal planes further dictate a rhythmic continuity throughout the building. Building's scale is rather modest in comparison to its site and the surrounding landscape and the smooth texture of the facade helps its integration to the environment. (Figure 4)
