It was optimized that the lateral stiffness of an under-designed super high-rise building located in 0.30g seismic fortified regions, with 58 stories above the ground and 235.80 meters total structural height. By having adequately adjusted the wall thicknesses of the core-wall and the cross sectional dimensions of the frame columns, a more reasonable structural scheme was obtained. It was then discussed the suitable numbers and heights of the strengthening stories set for controlling the building’s story drifts. Finally, it was explored that the efficiency of seismic input energy dissipation via viscous dampers installed at the right places of the structure.

System Selection

The most important aspect of any successful structural construction is the formwork system. Formwork itself defines as the temporary structure into which the concrete placed to obtain its desired shape and gains its weight to withstand against various loading conditions. This paper focuses on the two parts 1. Identified different formwork systems using in Indian construction industry for high-rise building construction and 2. Explanations of the decision support system for formwork system so that a decision-maker decides or makes the right choice for the selection of formwork system. This study employed a literature review approach (journal paper, research paper, technical articles & notes, and white paper). The methodology divided into two parts; firstly, the identification of the formwork systems used in the construction industry and secondly, to study a brief about decision support system and for formwork system by which the ease to make a decision support frame for the formwork system selection. This paper reflects the different formwork system typology used in the construction industry for high-rise buildings. The outcome of this paper helps to establish the baseline to develop decision support for the formwork system selection.

Universities contribute to the creation of a knowledgeable and skilled national workforce. The world over, universities are hailed as one of the old forms of organizations that have been instrumental in contributing to the development of many nations by producing skilled and intellectual human resources needed to produce goods and services. For this role fulfillment, the universities must ensure student satisfaction as students are the core of the very existence of universities and most important stakeholders in the higher education scenario. Moreover, student satisfaction is likely to enhance not only the better teaching-learning process, knowledge transfer, but also the competitiveness of the universities. This is all the more relevant and probably the best way to adopt for the university to play their role effectively and also is competitive in emerging economies. Hence, adopting a quantitative descriptive cross-sectional research methodology, this study aims to deliberate on how student satisfaction is the right approach and can drive university competitiveness.

High Rise Building

Seismic response of a high-rise building under rare earthquake is numerically investigated in the paper. The Height of the building is 266m, which goes beyond the limit of 150m in Chinese standard, so nonlinear analysis should be performed to investigate its elasto-plastic behaviors under severe earthquake excitations. In the finite-element model for analysis, beam-column members of the structure are simulated by beam elements, while the core tube is simulated by shell elements. The concrete damage plasticity model is used for concrete members, while the kinematic hardening rule is defined for steel beam-column members. Four sets of earthquake wave, including 3 sets of strong earthquake records and 1 set of artificial wave, are adopted in the analysis. The analysis results show that, under severe earthquakes, steel frame members and steel truss members in the strengthened floors keep elastic. Severe damages are detected in almost all coupling beams in the core tube, as well as shear-walls near strengthened stories, where lateral stiffness would decrease seriously. Through the investigation, it is also found that the largest story drift is less than the maximum allowable value in the Chinese code for seismic design of buildings. So it is concluded that the high-rise building will not collapse when the place is subjected to severe earthquakes. Besides, some design suggestions are proposed according to nonlinear dynamic analysis in the paper.

The article presents the results of calculating the performance indicators of the dispatcher service of a high-rise building as a queuing system with an unlimited queue. The calculation was carried out for three models: with a single control room and brigade of service, with a single control room and a specialized service, with several dispatch centers and specialized services. The aim of the work was to investigate the influence of the structural scheme of the organization of the dispatcher service of a high-rise building on the amount of operating costs and the time of processing and fulfilling applications. The problems of high-rise construction and their impact on the complication of exploitation are analyzed. The composition of exploitation activities of high-rise buildings is analyzed. The relevance of the study is justified by the need to review the role of dispatch services in the structure of management of the quality of buildings. Dispatching service from the lower level of management of individual engineering systems becomes the main link in the centralized automated management of the exploitation of high-rise buildings. With the transition to market relations, the criterion of profitability at the organization of the dispatching service becomes one of the main parameters of the effectiveness of its work. A mathematical model for assessing the efficiency of the dispatching service on a set of quality of service indicators is proposed. The structure of operating costs is presented. The algorithm of decision-making is given when choosing the optimal structural scheme of the dispatching service of a high-rise building.

Tall building development is rapidly growing almost everywhere in the world acquainting new difficulties that need to be met with, through engineering evaluation. In tall buildings, lateral loads generated by earthquake or wind load are frequently resisted by providing coupled shear walls. But as the height increases, the building becomes taller and the efficiency of the tall building greatly depends on lateral stiffness and resistance capacity. So, a system called outrigger is introduced which improves overturning stiffness and strength by connecting shear wall core to outer columns. When the Structure is subjected to Lateral forces, the Outrigger and the columns resist the rotation of the core and thus significantly reduce the lateral deflection and base moment, which would have arisen in a free core. During the last three decades, numerous studies have been carried out on the analysis and behaviour of outrigger structures. But this question is remained that how many outriggers system is needed in tall buildings. (Using Staad-Pro)

High Rise Building

Majority of office buildings in China are appeared in forms of high-rise buildings and have a character of high construction-scale and high energy-cost. The daylighting in office can not only save the energy, but also meet the physical and psychological needs for eyes, and finally lead to higher work efficiency. Solving the daylighting problems in the high-rise office buildings is urgent. The core position in the high-rise building is an important factor to affect the light in office. In this paper, the author analyses the lighting characteristics of three types of the core position, which is core in the center of the building, core at the peripheral of the building and the core separated from the building. Combined with the natural lighting assistance measures, some design essentials were raised in this paper.

Abstract The target article carefully describes the memory system, centered on the temporal lobe that builds specific memory traces. It does not, however, mention the laterality effects that exist within this system. This commentary briefly surveys evidence showing that clear asymmetries exist within the temporal lobe structures subserving the core system and that the right temporal structures mainly underpin face familiarity feelings.
