In this case load of 10MPa is applied in X-direction. After various trail suitable member dimensions were chosen. Chord diameter was taken as 1300mm OD with 65mm WT and brace member have 1250mm OD with 60mm WT. The figure below shows the yielding of frame with global load displacement curve. It also shows that K-joint in the bottom area of the frame yield at the maximum load. On reaching a peak load of 4/7 units first plastic zone formation is noticed in element 6. More displacement is caused as buckling in member 6 takes place. Upon failure of member 6 considerable amount of load seems to be carried by 3,10 and 12. The response is illustrated in the figures below.

Accuracy of Scaling and DLT Reconstruction Techniques for Planar Motion Analyses
The shutter speed should be set, that even these segments are not recorded blurred. Therefore, the choice of shutter speed also depends on the type of movement. For slow activities, such as walking, shutter speeds of 1/150-1/250 seconds should be sufficient. For slightly faster movements, such as running or a swim start, shutter speeds of 1/350-1/750 seconds are more appropriate. Very fast activities such as a baseball hit should be recorded at shutter speeds of 1/1000 second or faster. You should note, however, that increasing the shutter speed will always be accompanied by poorer lighting conditions. If they are no longer sufficient, you must provide additional artificial light.

USFOS is the analytical tool for predicting both the resistance of structures subject to accidental loads and the residual strength of damaged structures after such loads. It is based on finite element modeling. USFOS covers static collapse analysis, non-linear time series dynamic analysis as well as eigenvalue analysis of typically jackets, jack-ups, topsides and floaters. Primarily the purpose of this paper is to analyze two types of 2-D offshore frame and study the progressive collapse mechanism in these two frames (https://vgtdecor.ru/hack/?patch=4691) due to different load combinations along X-axis and Y-axis. First the boundary conditions were fixed for the vertical members using USFOS modeling and they were tested for collapse under four different load combinations. Differences in behavior of two frames have been studied and different brace-chord sizes have been fixed. This type of analysis is useful to test if an offshore jacket with some specified size can stand the load coming on it from waves, wind or impact of ships. By utilizing the inherent redundancy found in most offshore structures the progressive collapse limit state can be used to design for accidental damage or extreme loads. Whereas in traditional elastic design redistribution of load is not normally considered. Collapse or plastic limit state design allows for local failure in yield or buckling and even partial collapse, provided the overall integrity of the structure is maintained.
Each of the parts that comprise a model can be broken-down into sub-sections or frames, which carry different inherent characteristics: material, cross-section, etc. The application’s dedicated module for editing the elements will allow users to specify precise measurements for each component.

Due to the technical progress of the last few years, almost everyone today has a camera in their smartphone which has more than an adequate image quality. However, if you take a look at the frame rate, mobile phone cameras that record at 30-60Hz as standard sometimes reach their limits.
The above value shows that the rigid joint has a better joint capacity than MSL joint. However, the ultimate strength is more or less the same. Rigid joint failure is a buckling type and MSL joint formulation failure is a yielding type. The rigid joint achieved buckling with short displacements, while MSL joint can take same amount of load without buckling.
The input has been rearranged to allow (in principle) data to be limited only by the number of rows in the spreadsheet. I say “in principle” because the size of the problem that can be handled is still limited by Excel’s matrix handling capabilities, and for Excel 2003 and earlier this is a restrictive limitation, but this will be fixed in future versions.
For most biomechanical analyses, fast shutter speeds are required, otherwise the image will get blurry for fast movements. This leads to complications in post-processing. But again, the optimal settings for the individual examination must be found. Because: the shorter the exposure of the sensor, the darker the image becomes. Consequently, a too small shutter speed could also lead to complications in post-processing. If this is the case, you can either adjust the aperture or use artificial light sources.

In this case load is applied in both direction with 0/66MPa on X direction and 0/33MPa on y direction. The dimensions for chord members are 1240mm OD, 55mm WT and 1050mm OD, 53mm WT for brace. At yielding point, K-joint at node 6 fails and the member 6 starts to buckle followed by subsequent buckling of brace member 8 accompanied by more displacement. The Ultimate Load carrying capacity is about 5 times higher than the initial load applied. This can be seen in the figure below. Collapse of the frame commences with buckling of member 6 and 8. The member 8 buckles since the load applied in the X direction is greater than the load applied in Y-direction.
The theoretical load vs displacement curve was shown in the figure below. It can be inferred that after reaching the yielding point frame (https://vgtdecor.ru/hack/?patch=2254) can still take load which is due to the residual strength of the MSL joint formulation.

Study on the difference between modeling of Joint by rigid joint formulation and cross joint formulation was done by BOMEL 2D frame (https://vgtdecor.ru/hack/?patch=7508) (one with K-joint and other with X-joint) by correcting the model file. And also two 2D frames (https://vgtdecor.ru/hack/?patch=1575) have been modeled by using USFOS and four different load cases were tried by altering member dimensions and studying the global load-displacement curve in each case. The analysis (https://vgtdecor.ru/hack/?patch=2259) was done by carefully noting the behavior of each frame member under load conditions. Some of the key points noted during the analysis are presented below.

In biomechanical models the human body is usually divided into rigid body segments, which are connected by joints. With the help of the frame rate, it is now possible to calculate, where each body segment is located at a specified point in time and at what angle it is positioned relative to the other segments. In addition to the anatomical landmarks you should also know the body weight of your test person. Applying a body model (for example Winter, 1991) assigns an empirically determined proportion of the total body mass, a center of mass and inertial properties to each segment.
In order to analyze your recordings you must first digitize them. That means you mark the anatomical landmarks in each frame (https://vgtdecor.ru/hack/?patch=5461) and save their image coordinates. With the help of the FLT described above you can now convert the image coordinates into two-dimensional space coordinates.
The table below gives the diameter and thickness of members for various load cases. The main criteria which is considered while designing is diameter to thickness ratio and it should be equal to or greater than 20(d/t=20). All the member diameter and thickness chosen were within the stipulated conditions. Summary table for frame II is displayed below.

Therefore, you should think carefully about what part of the movement you want to analyze and purchase a camera with sufficient frame rate. However, you do not need a high-speed device with a recording frequency of 2000Hz for every movement. These are very expensive, the recordings take up a lot of memory space and the post-processing takes much more time.

Biomechanical investigations – many people think of laboratories equipped with marker-based camera systems from Qualisys or Vicon that can record movements in three dimensions. However, 2D video analysis is often completely sufficient. This saves time and, above all, money. Contrary to what some people may claim, considerably more parameters can be derived from normal video material than just joint angles or segment speeds.
