Study on the Ductility of T-Shaped Short-Limb Shear Walls (I)

In this paper, the author takes on the experiment of low cyclic load and analyzes the tenacity and ductility characteristic of the specimen, and simulates the elastic-plastic failure modes of T-shaped short-limb shear walls by using the finite element software ABAQUS and applying the damage plasticity model to select the proper unit type. Results indicate that the mechanical behavior of T-shaped short-limb shear walls under the condition of horizontal load force may be accurately simulated by the method proposed in this paper.

Study on Strength Characteristics of Reinforced Soil by Cement and Bamboo Chips

Soft ground with low bearing capacities is found to large areas in the world. In order to increase the bearing capacity of soft ground and to decreases settlement, some methods were developed for improving the mechanical properties of ground. As a stiffener of soil improvement, bamboo chips were used in this study. Bamboo is one of the fastest-growing plants on Earth and with a large distribution around the world. As a natural material, it is even better for environment and has excellently mechanical characteristic. The bamboo chips were mixed into the test specimen as a stiffener of soil improvement. Unconfined compression test were performed with test specimen, then mechanical characteristics of reinforced soil by cement and bamboo chips were investigated. From the test results, the strength and ductility characteristic of soil improvement are rather better when the bamboo chips are mixed.
