Natural Calamity

Earthquake happens all around the globe and it is a natural calamity and can occur across the world. It affects the structure by producing tough ground signals. To overwhelmed the Earthquake there is establishment of Shear wall and Bracing to increase the crosswise stiffness, ductility of the structure. To plan a building storey drift and crosswise displacement are crucial. The building is analyzed by Linear static and Linear dynamic method by E-tab software. In present paper G+25 multistoried building is analyzed by insertion of Shear wall and bracing at Corners, End and central core of the structure. The responses like Displacement, Storey drift, Time period and Base shear is calculated and equated.

Tall buildings structure has been a considerable increase in both residential and commercial as well as modern Trend structures. There are two systems comprise the most attractive and commonly used now a days are flat slab and shear wall system. Flat slab is most widely used system in reinforced concrete construction in offices, industrial buildings etc. It supports floor slab without beams. When it comes to seismic performance or lateral force flat slab tall buildings without shear wall is relatively less when compared to with shearwall.in this study I have done two models of flats slab tall buildings one with shear wall and another one without shear wall by using ETABS software. The comparison of analysis results will take place in order to see how both a buildings are performing under lateral and seismic loads and finding a seismic parameters like time period, base shear, lateral displacement, and storey displacement are checked out.

ABSTRACTShare of Indonesia's export value of natural rubber in the international market is almost always below Thailand, which is one of the competiting countries. The others countries began to become a threat to Indonesia because their exports share of natural rubber showed an increasing. This indicates that there is intense competition in the international market. As a country with the largest plantation area in the world, Indonesia should be superior. But this can be an opportunity to be able to compete in the world market so it is important to be managed more deeply so that it can create competitive advantages that can increase competitiveness. This study aims to determine the position of the competitiveness of natural rubber exports for the three countries of ITRC in the international market. The analytical method used is dynamic RCA. The results showed that all products of natural rubber coded HS 400110, 400121, 400122, 400129 and 400130 were experiencing a decline in growth in the export share of the three countries of ITRC : Indonesia, Thailand and Malaysia, but the market demand conditions for these products were declining in that time period.

The Relationship

China's export-led growth is rooted in China's double transition of demographic transition and structural change from industrialization. Accession to the WTO has allowed China to fully integrate into the world system and capture the gains of its comparative advantage in abundant labor supply. Structural change has a dampening effect on the Balassa–Samuelson effect so as to sustain China's competiveness in the world market. The double transition will take 10 to 15 years to finish; in this time period, China will likely continue its fast export-led growth. Along the way, export-led growth has also created serious structural imbalances highlighted by underutilized savings, slow growth of residential income and domestic consumption, and a heavy reliance on investment. This linkage requires new thinking when global imbalances are to be tackled.

Structural Engineers

Structural engineers routinely use rational dynamic analysis methods for the seismic analysis of buildings. In linear analysis based on modal superposition or response spectrum approaches, the overall response of a structure (for instance, base shear or inter-storey drift) is obtained by combining the responses in several vibration modes. These modal responses depend on the input load, but also on the dynamic characteristics of the building, such as its natural periods, mode shapes, and damping. At the design stage, engineers can only predict the natural periods using eigenvalue analysis of structural models or empirical equations provided in building codes. However, once a building is constructed, it is possible to measure more precisely its dynamic properties using a variety of in situ dynamic tests. In this paper, we use ambient motions recorded in 27 reinforced concrete shear wall (RCSW) buildings in Montréal to examine how various empirical models to predict the natural periods of RCSW buildings compare to the periods measured in actual buildings under ambient loading conditions. We show that a model in which the fundamental period of RCSW buildings varies linearly with building height would be a significant improvement over the period equation proposed in the 2010 National Building Code of Canada. Models to predict the natural periods of the first two torsion modes and second sway modes are also presented, along with their uncertainty.

Seismic Vibrations

The reinforced concrete structures, not designed for seismic conditions, amid the past earthquakes have shown us the significance of assessment of the seismic limit state of the current structures. During seismic vibrations, every structure encountered seismic loads. Seismic vibrations in high rise building structure subjects horizontal and torsional deflections which consequently develop extensive reactions in the buildings. Subsequently, horizontal stiffness can produce firmness in the high rise structures and it resists all the horizontal and torsional movements of the building. Therefore, bracing and shear wall are the mainstream strategies for reinforcing the structures against their poor seismic behaviours. It is seen before that shear wall gives higher horizontal firmness to the structure when coupled with bracing however it will be another finding that in building model, which location is most suitable for shear wall and bracing to get better horizontal stability. In this study, a 15 story residential reinforced concrete building is assessed and analyzed using building code ACI 318-14 for bracing and shear wall placed at several different locations of the building model. The technique used for analysis is Equivalent Static Method by utilizing a design tool, finite element software named ETABS. The significant parameters examined are lateral displacement, base shear, story drift, and overturning moment.

The article examines and analyzes the changes in the world of culture and art that have involved the postmodernism era, which arose during a period of rapidly changing moods in society, which accept the appearance of culture, but are absolutely alien and ugly, bearing the decline and destruction. Art, which is a kind of mark of the epoch and a reflection of morality, established stereotypes, and lifestyle, has experienced many revolutionary trends caused by the demand of a particular time period. In modernculture, there is a negative trend in the development of artistic, literary, and cinematic production, everything is oriented to the market needs. Canons are being collapsed, content is being simplified, and technologies are being violated. Culture and art began to meet individual human needs, acquired a commercial character and became subject to the influence of the customer and the consumer.What is a "mass" culture? How much does the understanding of art depend on a person's wealth and education? For whom is culture now intelligible? How does the society standard of living influence culture and art in general?

This article represents an analysis of efficiency of Ukrainian democracy within the framework of three popural indices of democracy – The Economist Democracy Index, Freedom In the World index and Polity IV. Comparative analysis shows the core factors which bring three different democratic concepts, used in the indices, to the integral unity. Finding correlation between factors of Ukrainian democracy, measured in the indices through a certain time period (2006-2018), helps getting integral look at the problem of non existent universal theoretic base for understanding democracy. The basic idea of the analysis, represented in this article, shows that different factors, used by indices in measuring democracy, do not evenly correlate in practice, though they represent holistic approach to the essence of democracy. Choosing specific theoretical approach of understanding democracy makes it hard for indices to fully measure real democracy. This analysis aims at searching correlation in different basic factors of democratic models, used by indices with different approaches. As the result of the analysis the article ranks a number of basic factors, used in three popular indices of democracy, according to the strength of correlation of these factors with other factors of the index they represent and with the final score of the index. Integral choice of the basic factors, which correlate with the change of Ukraine’s democratic trends according to the three indices, covers several dimensions of democratic model. Ukrainian democratic trends in the specific time period (2006-2018), as the analysis shows, from integral point of view correlates the most with the changes in electoral process and pluralism, civil liberties and legal restrictions of the executive power. Political culture, political participation and individual rights show weak correlation with Ukrainian democratic trends within the period of time, chosen for the analysis.

Allocating appointment slots is presented as a new application for market design. Online booking systems are commonly used by public authorities to allocate appointments for visa interviews, driver’s licenses, passport renewals, etc. We document that black markets for appointments have developed in many parts of the world. Scalpers book the appointments that are offered for free and sell the slots to appointment seekers. We model the existing first-come-first-served booking system and propose an alternative batch system. The batch system collects applications for slots over a certain time period and then randomly allocates slots to applicants. The theory predicts and lab experiments confirm that scalpers profitably book and sell slots under the current system with sufficiently high demand, but that they are not active in the proposed batch system. We discuss practical issues for the implementation of the batch system and its applicability to other markets with scalping. (JEL C92, D47)
