Dynamic characteristics of tensioned cable-membrane structures are analyzed and the influence of prestress on membrane,prestress on cable,ridge cable,sag-to-span ratio,span of structure and the supporting system is discussed.

The steel tube structure and curtain wall supporting system of Tianjin Taida Civilian Plaza\'s pyramid consists of two vertical facades and an inclined plane.

To realize the support system for glass curtain wall is a technique focus.

Four types of support systems have been summed up in light of continuous curved box-girder bridge supports used,the characteristics of each support system have been analyzed.

Study on influence of system conversion of construction to deformation of PC continuous beam bridge;

The article introduces the technical flow of the structural system conversion of Fenghua Bridge on Haihe River and the stress deformation control in the course of its implementation,and the preparation and selection of the hanger rod stretching technology.

As the huge potential energy will release after the system conversion and relieving the temporary constraint,the slipping of main girder of unidirectional sloping cable-stayed bridge with floating system will appears,the construction and the whole bridge stability will be influenced.
