The Impact

In recent years, as the portal frame’s height toward higher and the span toward wider, the influence of wind vibration becomes more and more prominent among the portal frame structure. In the design of the portal frame, there are many different opinions on whether considering the impact of the vertical wind vibration to the portal frame. This paper taking a true engineering as an example, using finite element software to establish the solid model of the portal frame structure, selecting the junction of purlin and roof as a node of imposing vertical fluctuating wind load, we made numerical simulation analysis of vertical wind vibration. The simulation results will be compared with data of the internal forces and deformation under the average wind pressure. The results showed that: vertical wind vibration has a prominent effect to the portal frame and should be considered in the design.

Packet Scheduling Algorithm

This paper puts forward a new dynamic round-robin (DYRR) packet scheduling algorithm with high efficiency and good fairness. DYRR algorithm introduces dynamic round-robin concept, that is, the allowance given to each of the flows in a given round is not fixed, but is related with the number of bytes sent of this and other flows of the last round scheduling. The time complexity of the DYRR algorithm is O(1). Results from performance simulation analysis shows that DYRR algorithm can effectively smooth output burst, realize fair scheduling, and have a good time delay characteristic.

Improvement Measures

Reinforced concrete eccentric frame - shear wall structures has been widely used in Engineering, but this structure is mostly used for high-rise structure. Depending on experimental study will be unable to accurately draw the seismic reflection of structure, it needs to use the simulation software to study the seismic performance of high-rise structure. In this paper, by using ANSYS finite element analysis software to establish the numerical model which is based on the test model to carry out the seismic performance simulation. Then, through the improvement measures to get the measures for improved seismic performance.
