The diagrid structure system has become an encouraging alternative for the construction of tall buildings partly because of the aesthetic reason. Structurally, the system also interesting because its diagonal intersecting members are capable of resisting vertical and lateral forces efficiently. This research compared the design of steel tower building using diagrid (DIA) system and the more commonly used systems, moment frame (MF) and braced frame (BF). Numerical modelling using finite element software ETABS were conducted to design a 10-story building of 15x15m with total height of 50 meters. The seismic behaviors of all models were compared under the same loading conditions. From the analysis results the DIA model showed superior seismic behavior followed by BF and MF. The DIA model was not only stiffer than the others, but also required smaller volume of steel.

System identification(SI) techniques using dynamic responses and behaviors of structural systems become an outstanding issue of researchers. However the conventional SI techniques are identified to be non-practical to the complex and tall buildings, due to limitation of the availability of an accurate data that is magnitude or location of external loads. Thus a technique to estimate structural properties of building without input measurement data and using limited response is essential in structural health monitoring. In this study, the improved least square method for damage detection is proposed and verified by shaking table tests on three-story plane frame steel structures. In results damage detection was performed in each member level.

High Rise

Advances in construction technology, materials, structural systems and analytical methods for analysis and design facilitated the growth of high rise buildings. Structural design of high rise buildings is governed by lateral loads due to wind or earthquake. Lateral load resistance of structure is provided by interior structural system or exterior structural system. It is very important that the selected structural system is such that the structural elements are utilized effectively while satisfying design requirements. Recently diagrid structural system is adopted in tall buildings due to its structural efficiency and flexibility in architectural planning. diagrid structure consists of inclined columns on the exterior surface of building. Due to inclined columns lateral loads are resisted by axial action of the diagonal. lateral shear can be carried by the diagonals on the periphery of building. Analysis and design of 30 story diagrid steel building is presented. A regular floor plan of 36 m × 36m size is considered. ETABS software is used for modeling and analysis of structural members. All structural members are designed as per IS 800:2007 considering all load combinations. Earthquake is considered for analysis of the structure. Load distribution in diagrid system is also studied for 36 storey building. Similarly, analysis for the different diagrid pattern is carried out. Comparison of analysis results in terms of time period, top storey displacement and storey drift is presented in this paper.

The choice of cost-effective method of anticorrosive protection of steel structures is an urgent and time consuming task, considering the significant number of protection ways, differing from each other in the complex of technological, physical, chemical and economic characteristics. To reduce the complexity of solving this problem, the author proposes a computational tool that can be considered as a subsystem of computer-aided design and used at the stage of variant and detailed design of steel structures. As a criterion of the effectiveness of the anti-corrosion protection method, the cost of the protective coating during the service life is accepted. The analysis of existing methods of steel protection against corrosion is performed, the possibility of their use for the protection of the most common steel structures is established, as well as the estimated period of effective operation of the coating. The developed computational tool makes it possible to choose the best method of protection of steel structures against corrosion, taking into account the operating conditions of the protected structure and the possibility of using a protective coating.
