 The major purpose of this study is to justify construction method of a hybrid structure in core area with construction complexity due unsafe excavation conditions and tries to define its rigidity and strength. Both RCC and Frame structure transfer same load to ground through foundation but the transfer mechanism varies. In some practical condition, building construction should be carried out in compact areas with unsafe adjoining building where adequate excavation for foundation cannot be carried out. In such cases, one bay hybrid structure is proposed for construction with combined RCC frame structure and load bearing walls. In these combined cases, both structures works as same unit to transfer building load but the transfer pattern varies. The variable load transfer pattern is due to discontinuity in structural system which also effect on seismic response of the building. The placement of a masonry load bearing structure in RCC frame structure varies design of all structural components of the building. To study actual behavior of hybrid structure in various load condition and introducing cost minimization techniques of buildings structural analysis was carried using ETABS 2016 with composite structural arrangement and with induction of load bearing wall as structural component. By which seismic behavior of building in both cases was obtained as well as reduction in rebar percentage and dimensional reduction of structural components can be achieved.Journal of the Institute of Engineering, 2017, 13(1): 117-124

To improve work efficiency of cabin and solve the contradiction between load bearing and mass, combining parametric modeling and optimization theory,the influence curves of load bearing on mass are proposed. Applying stress state theory, combining distortion energy theory criterion and Tsai-Wu failure criterion, shells load bearing is theoretically analysed. Contrast results are, in the same load condition, compared with alloy, the weight of composite reduces 46.2%;in the same weight condition, the load bearing of composite increases 75%. At present, the cabin load bearing is 0.04MPa, to improve work efficiency, increasing to 0.055MPa and replacing alloy by composite, the load bearing increases 37.5%, while the weight reduces 26.1%, then the contradiction between work efficiency and mass is coordinated.

The torque stability and shutdown control of electric learner-driven vehicle (ELV) in the condition of motor load suddenly changing make the ELV has the same clutch handling characteristics with the traditional vehicle, and this makes the ELV popularization possible. A special control method is put forward in this article to achieve the consistency with the mechanical properties of engine. A multiparameter control model to identify the real condition of clutch handling by driver is builded with fuzzy control law. The torque stability and shutdown control of the motor with the load raising rapidly condition are approached by the adjusting of armature voltage with PWM control law.

Relevance. A beam-column joint is a crucial zone in any frame structure that transmits the forces at the end of the members in the panel zone. The connection between the joints may be assumed as rigid or flexible one and it is not an ideal one to predict the actual behavior of the joint section. Methods. The displacement along the joint section is the most critical one that has to be taken care while designing the structure. In this paper, the flexibility of the reinforced concrete joints was studied under two different cases: in first phase, building having 3 storey including ground floor was taken and is analysed using SAP 2000 and secondly third floor shear wall with l hollow concrete mesh of column section was analyzed in same software and the flexibility of the joints was tested in terms of its stress and displacement parameters using different approaches such as link mass property, end length offset zone, panel zone rotational spring stiffness property. The results obtained from the two cases were analyzed with consideration of parametric study and variation of the stresses with displacement and are shown with comparative graphic.

For the cast-steel joint of large span roof system, the main difficulties of prototype stress test encountered are the large scale of the structure system, large loading system and large supporting system, etc. The hydraulic jack of high tonnage is adopted to apply the load. The frame structure of channel steel is used to fix the cast-steel joint and the loading system. The reverse loading system is elaborated to simulate the axial tensile force. So prototype stress test on the cast-steel joint of large span roof system is accomplished successfully. The test results show that, under the designing load condition, cast-steel joint is in a linear elastic state, the structure is globally safe; the maximum surface stress of cast-steel joint is adjacent to the crossing point of steel pipes; the stress value of test is well coincident with one of finite element analysis. This test device system is especially suitable for the stress state test of large components, and can also provide important reference to the similar projects.
