The development and engineering applications of beam-string-structure are introduced and a new space beam-string-structure with outer truss torus is proposed. The new structural system is to reduce the space occupied by roof structure and could be laid by the rigid roofing material easily. Three types of annular tensile cable-truss structure were given. Sunflower-patterned space beam-string-structure was taken as an example and its static behavior under full-span load and half-span load was analyzed. The efect of prestress level on static behavior of the structure was studied. The results will provide a reference for a further design and project application of such structure.

Bicycle Stadium in Jinan Olympic Sports Center adopts spatial truss structure with steel tube. The design and analysis of the roof structure are introduced in detail. By applying the program SAP2000 and STCAD, the static and dynamic properties of the roof structure are obtained. In addition, the design of the cast steel support joint are studied, which focuses on analyzing the static behavior of the typical cast steel support by using the program ANSYS. The results prove that the spatial truss structure is reasonable, which can satisfy the requirements of safety of the building. For the complex support joints subjected to large reaction forces, cast steel support joints can meet the architectural and structural requirements. The research results in this paper can provide references for the design of similar engineering.

This article studies the cavitation performance and preventing method of the hydromechanical pressure compensation independent metering system (HPCIMS). Compared with the conventional load sensing system (CLSS), the meter-in and meter-out orifices of HPCIMS can be regulated independently. A quasi-static behavior analysis of cavitation performance was applied to the HPCIMS and CLSS. The meter-in pressure equation of HPCIMS showed that keeping the ratio of the meter-in and meter-out orifices greater than the minimum value can avoid the cavitation phenomenon. Systems parameters were then kept as constant, and the key parameters related to cavitation performance of the two systems were compared by varying external force. Comparison results show that the cavitation phenomenon in the meter-in chamber of CLSS with the external active load is inevitable, but in HPCIMS, it can prevent the cavitation phenomenon by changing the ratio of the meter-in and meter-out orifices, so the HPCIMS has the cavitation prevention potential.
