The second Penang Bridge is a new bridge under construction in Penang, and will become the longest bridge in Malaysia and Southeast Asia. The purpose of this test is to estimate the bearing capacity of the form travelers in the second Penang Bridge. The pre-loading test simulates the construction stage of the typical edge beam and slab section. By observing the strain and deformation data of the form travelers, stress and displacement were analyzed to ascertain the performance and safety of form travelers and to provide evidence for the main beam alignment control in construction.

The structure form of the multi-pylon cable-stayed bridge is greatly different from that of conventional cable-stayed bridge with twin-pylon or single-pylon, which induces the mechanical behavior of multi-pylon cable-stayed bridge is also much different from that of cable-stayed bridge with twin-pylon or single-pylon. Combined with the Fanli Bridge in Yixing city of Jiangsu province, the load carrying performance of this type bridge is analyzed. The analytical results show that the internal force distribution pattern of main girder in this type cable-stayed bridge is different from that of in conventional cable-stayed bridge, also the internal force distribution pattern of both the different steel pylons in same bridge and the steel columns in same pylon are distinctive.

Mechanical behavior of box girder with corrugated steel webs in completion status of bridge was studied. Based on the cable stayed bridge of box girder with corrugated steel webs on Zhenshui Road in Xinmi City, finite element method (FEM) was applied to calculate and analyze vertical displacement of box girder, shearing stress of corrugated steel webs, normal stress and vertical deflection of concrete plates, longitudinal strain of box girder in completion status of bridge. The results show that vertical shearing stress of corrugated steel webs is approximately uniformly distributed along the height of box girder. Vertical deformations of corrugated steel webs play the dominant role in the whole box girder. Longitudinal strain of corrugated steel webs is smaller than that of concrete plate. Structural design method based on traditional theory that corrugated steel webs bear all the shear force is conservative. Keywords: box girder with corrugated steel webs; cable stayed bridge; deflection; stress; strain

Longitudinal assembled stiffness is the biggest problem for multi-pylon cable-stayed bridge. The longitudinal displacement and midspan deflection could be effectively controlled by setting horizontal cable at the top of pylon of multi-pylon cable-stayed bridge. This paper obtains the area and the cable force change formula of the horizontal cable through simplified model analysis of the mechanical behavior of setting horizontal cable at the top of pylon. The comparative analysis is performed by application of finie element model to discuss the effect of setting horizontal cable at the top of pylon of multi-pylon cable-stayed bridge.
