A new steel special-shaped lattice column (SSLC) was proposed, which can be used in prefabricated steel structure residence. The finite element models of four SSLC with different cross-section (L-shaped, T1-shaped, T2-shaped and X-shaped) were established under cyclic loading by using ABAQUS, in which the strength, lateral resist capacity and hysteretic behavior were analyzed. The results indicate that SSLC has adequate strength, stiffness and safety redundancy. Among the four SSLC, the SSLC with X-shaped has the best structural performance and seismic behavior.

Weight Structure

Because of environmental issues, the regulations on gas emission from fossil fuels become stricter. Some investigations are being carried out actively to change the fossil fuel power into electrical power. Researches on the reduction of weight in the transportation machine is also executed. Weight reduction is one of the methods of reducing the gas emission and increasing the range of electrically powered machines. The method of weight reduction includes the development of light weight material and light weight structure design method. FRP is the most representative light weight material. Among various FRP materials, (CFRP) has the highest specific strength. Light weight structure design method includes the method of designing the structure by converting the bonding method with bolts and rivets to adhesion method with the use of adhesives. In order to pursue the research on the adhesive structure design method, the research on adhesion exfoliation by using CZM needs to be carried out. There are the researches with various methods in accordance with the style of adhesion exfoliation load and material designs. In this study, the adhesion exfoliation on the tearing fracture of tapered double cantilever beam configuration was applied to the research. Research model was composed by applying the gradient angles of 6° and 8° to TDCB. The model with the gradient angle of 8° has less fracture due to adhesion than that of 8°. The basic data on structural design of adhesion structure were provided by comparatively analyzing the research models. This research was carried out by using finite element analysis method in this study. Finite element analysis method has the advantage of reducing the cost and time taken for experiments in researches. Therefore, the finite element analysis program, ANSYS, was used in this study.

The classical preload design method of prestressed frame of hydraulic presses is based on the assumption that the beams of the frame are rigid, which is not agree with practice. In order to eliminate the unbalance load of the frame of a 100MN hydraulic press due to improper prestressing, tie rod preload distribution in prestressing of the frame is researched with respectively mechanics of materials and the finite element methods. According to mechanics of materials and finite element analysis results, reasonable tie rod preloads and sequence of preloading are obtained and the unbalance load of the frame of the hydraulic press is solved. It also provides references for the preload design of prestressed frame of hydraulic presses.

All-terrain vehicle is famously used for various purposes. The design of the chassis of this vehicle is critical in determining the overall strength. In this paper, the design chassis frame for the use of all-terrain vehicle (ATV) is presented. In designing the chassis frame, a proper design method was employed. Finite Element Analysis (FEA) was utilized to determine the maximum stress and displacement of the frame when a particular load is applied onto it. Structure modifications need to be done if the chassis frame could not sustain the applied load. After the design process is completed, the fabrication of the frame is conducted by students of the engineering faculty. The fabricated frame will be used as the main part for a project of which a complete ATV will be developed. The main purpose of the project is to instill the interest among the student in engineering through the application of classroom.
