Abstract Although there are many mainstream reinforcement connection methods, the realization of force transfer between reinforcement is the starting point of all connections and the most important inspection standard. Aiming at the vertical connection of the fabricated shear wall, this paper proposes a new type of additional connector connection, and two fabricated shear walls connected by new types of additional connectors and a cast-in-situ shear wall were established. The dimensions and material parameters of the fabricated shear wall connected by the new additional connector were the same as those of the cast-in-situ shear wall. The finite element software ABAQUS is used to perform static finite element analysis on fabricated shear walls and cast-in-situ shear walls connected by new additional connectors. By comparing the static finite element simulation results, the results show that the new additional connector can ensure the effective force transfer of reinforcement.

Background and Objectives. A key factor for the long-term function of a dental implant is the manner in which stresses are transferred to the surrounding bone. The effect of adding a stiffener to the tissue side of the Hader bar helps to reduce the transmission of the stresses to the alveolar bone. But the ideal thickness of the stiffener to be attached to the bar is a subject of much debate. This study aims to analyze the force transfer and stress distribution of an implant-supported overdenture with a Hader bar attachment. The stiffener of the bar attachments was varied and the stress distribution to the bone around the implant was studied. Methods. A CT scan of edentulous mandible was used and three models with 1, 2, and 3 mm thick stiffeners were created and subjected to loads of emulating the masticatory forces. These different models were analyzed by the Finite Element Software (Ansys, Version 8.0) using von Mises stress analysis. Results. The results showed that the maximum stress concentration was seen in the neck of the implant for models A and B. In model C the maximum stress concentration was in the bar attachment making it the model with the best stress distribution, as far as implant failures are concerned. Conclusion. The implant with Hader bar attachment with a 3 mm stiffener is the best in terms of stress distribution, where the stress is concentrated at the bar and stiffener regions.

PurposeThe sheathing panels of traditional light wood frame shear walls mainly use oriented strand board (OSB) panels, and the damage of the traditional walls is mainly caused by the tear failure at the bottom corner of the OSB panel. In order to improve the lateral performance of the traditional light wood frame shear wall, a new type of end narrow panels reinforced light wood frame shear wall is proposed.Design/methodology/approachThe monotonic loading tests and finite element analysis of nine groups of walls, with different types of end narrow panel, types of fasteners used on the end narrow panels and the end narrow panels edge fastener spacing, are carried out. The effects of different characters on lateral performance of light wood frame shear walls are reported and discussed.FindingsThe failure modes of the wall reinforced by parallel strand bamboo narrow panels with 150 mm edge nails spacing are similar to the traditional wall. Conversely, the failure modes of other groups of walls reinforced by end narrow panels are the tears of the bottom narrow panel or the bottom beam. The end narrow panel reinforced light wood frame shear wall can make full use of the material property of sheathing panels. Compared with the lateral performance of traditional walls, the new-type end narrow panels reinforced walls have better lateral performance.Originality/valueA new type of end narrow panels reinforced light wood frame shear wall is proposed, which can enhance the lateral performance of the traditional light wood frame shear wall. The new-type walls have advantages of convenient operation, manufacture cost saving and important value of engineering application.

To enhance the structure strength and working life of the existing ladder-type chain connector, and chain connector productivity and manufacture craftwork. The ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of ladder type chain connector. And the static and dynamic experiments are carried on several samples. Finite element simulation results show that the main part of stress concentration is in teeth roots; experiments results show that the teeth roots are the fragile parts in the chain connector, the results of finite element analysis is conformed to the results of the experiments, thus that the ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of chain connector is reasonable. Because of the shortcoming of straight tooth chain connector, then promoted a chain connector of cambered surface tooth structure. Through the analysis, it shows that cambered surface can augment the contact areas in teeth, and prevent partial loading in teeth meshing. When chain connector manufactured, clamping tongs are quite complex, but the petal-type clamps structures are adopted, that can carry out volume-producing, thereby, and the productivity and processing precision are improved.

Concrete filled steel tubular (CFST) structure is a new type of structure. Assuming that concrete filled steel stub frame-shear wall is continuous elastic structure with infinite degree of freedom, free vibration equation is built. Furthermore, the effects of semi-rigid connection on natural periods and frequencies are studied. The formula to calculate the coefficient of natural periods is deduced. ANSYS is employed to determine the modal analysis. The results obtained from finite element analysis are consistent well with those obtained from formula. The results show that semi-rigid connections tend to increase the natural period. However, the effect on higher modes is negligible. The seismic design suggestions of the semi-rigid concrete filled steel stub frame-shear wall are proposed. The proposed methods may supply references for the engineers.
