：Chord dome structure is a new type of hybrid prestressed spatial steel structure system, which is often used in large-span structures. During the construction of the structure, it is necessary to apply prestress to the ring cable. Taking the chord dome roof of Hebei North University gymnasium as an example, the whole process of prestressed cable construction is simulated and analyzed by using the finite element software ANSYS. The hoop cable of the dome roof can slide freely in the hoop direction, and the attribute of free sliding in the ANSYS interface is "coupling". In this paper, two kinds of simulation models, coupling and uncoupling, are established to compare, and then to explore the influence of coupling on the construction process of string dome structure.

To overcome the shortcomings of assembly lightweight steel structure residential system in our country. A new type of lightweight energy-saving composite wall is proposed, which is composed by light-gauge shaped steel and thin panel. In order to investigate the load-bearing behaviour and failure mode of the composite wall, 4 wall specimens in full ratio were designed and manufactured. The experiment study is carried out under lateral and vertical loads. The results show that the self-drilling screw integrate the light-gauge shaped steel and thin panel to bear loads. The decrease of self-drilling screw spacing can effectively enhance the load-bearing capacity of the composite wall, and the best choice of the self-drilling screw pitch is 150mm. The composite wall has good bearing and deformation capacity, and it is suitable for applying to light weight steel residential system in our country.

This work deals with composite timber concrete structures. By combining timber and concrete in new type of composite material and using the best properties both materials, the high tensile strength of a timber and the high compressive strength of a concrete, depending of different building conditions we can find a lot o reasons for decision to apply this type of the structure in comparison to concrete or steel structure. Here, design methods and procedures for determination of load bearing capacity bar shaped connectors (fasteners) very often used as element connecting timber and concrete in composite structures will be given. The procedure will be exposed and explained according to the new fashioned methods collected as set of Euro-norms in Eurocode 5. The design equations in Eurocode 5 derived from Johansen's work are based on a rigid plastic behavior of the fastener under bending moments and the timber under embedding stresses and take into account the plastic moment capacity of the fastener.

For a new type of postearthquake temporary prefabricated lightweight steel structure proposed in this paper, mainly composed of steel frame, prefabricated hanger slabs, prefabricated hanger columns, reinforced concrete superposed slabs, etc., parameters of dynamic property for the structure, including natural frequency, vibration mode, damping ratio, etc., are determined by the test method. For prefabricated hanger columns and prefabricated hanger slabs, they are all produced with construction waste in factory and assembled on-site, which can form exterior walls. The united method, based on forced vibration method and ambient random vibration method, can quickly obtain accurate natural frequencies of the full-scale two-story experimental model. In this paper, damping oscillatory method is used to obtain damping ratio which can be determined only by the test method. In order to analyse the modal of the experimental model, a finite element model for the full-scale two-story experimental model is established, where the weight of prefabricated hanger slabs is assumed to be supported by prefabricated hanger columns, and the stiffness of prefabricated hanger columns is also increased. In addition, the connections between lightweight steel frame and prefabricated hanger columns are regarded as flexible connection. Comparing natural frequencies obtained from the finite element method with that obtained from the test method, magnification factor of stiffness for prefabricated hanger column is determined. In the analysis of modal for the full-scale two-story experimental model, the results show that the experimental model satisfies the requirement of design for seismic performance.
