The results of computation showed that the use of buckling restrained braces has led to several functional improvements, such as the increase in structure stiffness, reduction of story displacement, and improved energy dissipation ability when compared with the frame without such braces.
The basic data calculated for the original structure under the above condition was listed in Table 1.
Basic data calculated for the structure Story NO.
From the data list in Table 1, the lateral stiffness of the structure was insufficient.

For efficient acquisition of data at each exposure site, test specimens were set at angles of 0°, 45°, and 90° against the ground surface and, for the 0° and 45° angle settings, data acquisition was performed for the skyward- and groundward-facing surfaces.
The solid line refers to the regression relationship taking into account all the data plots.
Data points for the groundward surface at an inclination angle of 0° for test specimens at the University of the Ryukyus and Kyushu University and those for the skyward surface at the University of the Ryukyus, Kyushu University, and Kyoda are also plotted in Fig.5 as the reference data.
The regression line is in good agreement with the data plots.

The variogram of image reflects the randomness and structuredness of image data.
The range of variogram describes spatial scope of image data.
Apparently image noise data has strong randomness but the influenced scope of data space is small.
Conversely, image edge has strong structuredness but the influenced scope of data space is large.
For image data, range is small in strong noise area but large in scenery area.

Many approaches employ k-means clustering because of its computational simplicity, which allows to apply it to very large data sets.
It is the reduction in the uncertainty of one random variable due to the knowledge of the other.
We first explain the experimental setup, then show the results on different test data and compare with other methods.

The online application of domestic state estimation in Supervisory Control and Data Acquisition (SCADA) has gone through from the bad data check to the real-time cross-section data services.
(1)Telemetry value incorrect There are three main causes that lead to telemetry incorrect data of dispatching system, data acquisition error and error, data conversion and transmission error and data processing
The change of power grid operation will result in the data of rapid mutation and even the whole network data, and data transmission delay will lead to poor consistency of data used in state estimation.
The main steps are as follows: Step 1) Simulation computer simulate the daily operation data of power grid; Step 2) Data emulation layer to get the whole network operational data, simulate disturbance scenario and form various types of disturbance data; Step 3) Send disturbance data, which is formed in data simulation layer, to the testing platform and the SCADA application; Step 4) State estimation calculated according to the real-time data in SCADA.
Different ramp rate of load make the data obtained in state estimation is not consistent with the real-time data.

This paper researches the stochastic distribution feature and statistical parameter of geometrical imperfections for the data sources of above position deviation of joints by “abnormal data test method”.
By this contrast method, the above observation data can be taken as the important data source for studying the distribution feature and statistical parameter of geometrical imperfections for latticed shell structure.
The abnormal data eliminating method of t test rule will be mainly introduced as follows.
To study the stochastic distribution rule of joint position deviation for latticed shell structure, it needs a certain amount of raw data.
In particular, the sample average value of critical load Pμincreases more quickly according to the reduction of Cd. 4.

The data were logged at the frequency of 1000 Hz which means 60 data one second.
The force data at point A and B were recorded in the same experiments.
The data formed the red and black lines are chosen from one single experiment.
They are original data not the average data.
It is inferred from the present force data that larger amplitude can make penetration force lower.
