Chinese companies have actively expanded overseas. However, more and more companies, such as TCL, have found that technology sourcing cross-border M&A cost too much to threaten their survival, rather than achieving their goals. From reviewing previous literatures, we found that control, not the ownership, is the critical determinant. Control is the result of the bargaining power between the acquirer and the target company. Drawing on resources-based view, transaction cost theory and institutions theory, this paper reviews the influencing factors of bargaining power in the control and ownership, and proposes a model of control and ownership for Chinese enterprises technology sourcing cross-border M&A.

Seismic performance of corner joints without seismic details was analyzed by software ABAQUS, the results indicated that the reinforcement ration of the girders has great effects on the failure process and seismic behavior of corner joints. Beam Haunch Method was used to strengthen these joints, and then finite element analysis was conducted for the joints with unidirectional haunched beam (UHB)and bidirectional haunched beams(BHB). It was found that the bearing capacity of joints was significantly improved but the ultimate displacement and ductility factor were slightly affected by the haunch strengthening. The strengthening effect of bidirectional haunch was obviously superior to that of unidirectional haunch.

In this paper, the deformation fields of LY12 crack samples loaded by an SHTB are real-time investigated with the time interval of 10 µs by an optical system, which consists of a high-speed camera, a flash light, a frame grabber and a synchronization device with the delay-time less than microsecond. The cracks are preset by using the three-points bending method in a MTS fatigue machine. The crack is 2mm long with a flare angle of 60 degree. During the experiments, the dynamic deformation images are captured by the high speed camera and analyzed by newly developed software based on Digital Correlation theory. And the displacements fields near crack-tips according to the changes of the flare angle and radius during the impact process are obtained. Experimental results acquired in this paper are proofed, by compared with the theoretical calculations.

The feasibility of two new methods to reinforce the perforated section steel column was verified by two groups of axial compression tests, each group contained two specimens. The test results showed that reinforcement plates and original steel skeleton can work together effectively before specimens overall yielded whether front fillet weld or weld all around was adopted for the connection of reinforcement plates with the steel skeleton. After most of the measuring points on reinforcement plates yielded, reinforcement plates by front fillet weld plumped outward and deformed rapidly; however, no notable deformation was found for the reinforcement plates by weld all around. From the load–displacement curves of the specimens , the yield load of the section steel column by weld all around was a little larger than that of section steel column by front fillet weld. In general, the connection of reinforcement plates with the steel skeleton by weld all around was better than that by front fillet weld.
