Abstract: When the crane can’t work for the altitude of the high buildings, we can consider about the jacking system. Jacking system include some steel truss, a steel platform, some steel columns and so on. The steel platform is nearly the area with the concrete core tube, it provides a place for workers to wrap the rebar, to pure the concrete. This article combine the real engineering, detailing introduce when the jacking system meet a big wind load, how does it morph, and compare the margin with the code in China.

Abstract: According to the present situation of domestic and foreign firefighting rescue equipment for high-rise building and from the actual needs of the high-rise building firefighting, this paper brief analysis the current development of domestic and international firefighting rescue equipments problems and the trend of firefighting rescue robot. Combined with the special conditions of high-rise and super high-rise building fire scene, this paper introduces a breaking-window wall climbing firefighting rescue robot for high-rise and super high-rise, and introduces the operation mechanism of each part and the structure and the work principle of the main functional components.

Abstract: Based on the measure expense data from bill quantity of construction works of 38 high buildings in Xi’an, this paper applied the SPSS to analyze the linear regression between the total amount of measure expense and direct expense of project, the measure expense of civil work, bid price. On this basis, the forecasting model was built.

Abstract: Short-pier shear wall structure design in a high building was introduced in this paper, the author explored how to dispose various styles short-pier shear wall structure, the author expound practical application of conception design in short-pier shear wall structure design.

Abstract: With the socio-economic development and increasingly higher buildings, public concern is growing over high-rise fire evacuation issues. Considering the shortcomings of the existing escape device and methods, such as difficult speed adjustment, high demand for escaping skill, difficult unification of speediness and security, poor recycling etc, an integrated speed limited escape method is proposed by analyzing kinetics of high-rise evacuation. On one hand, the escape acceleration is limited by using centrifugal mechanism, on the other, according to the building height and people's weight, the landing speed of people is restricted by controlling the break height and braking force of brakes. The developed escape machine use the micro-controller to monitor the height and speed real-timely, control the brake automatically and start rope recycling mechanism after the landing, which achieves quick and safe escape. The experiment shows that when heavy object weighing around 75kg drops from a height of 14. 6m, the maximum speed reaches 3m/s, the landing speed is less than 0.5m/s and the falling time is within 7.5s, which achieves better escaping effect.
