Though the technologies are dynamically developing and there are a lot of research projects, there is still no general opinion on a glass-facade building among the European scientific community, architects and construction engineers. The increasing requirements to heat-protective qualities of translucent structures make us think of the necessity of a quantum leap both in technologies and in principal approaches to the development of architectural and constructive solutions of translucent shells. Together with economical features, the dynamics of heat-protective indicators’ increase show the tendencies to reaching the possibilities limits of mass glass units. The European construction practice usually solve this problem by developing sealed insulating glass units and by different conceptual solutions of the systems of translucent double facades. In the given article the basic theoretical principles and innovative engineering ideas are formulated dealing with the modern glass-facade building construction. “Green Building” conception is analyzed as a European new building philosophy.

Atrium Fire

In China the development pace of green building is becoming more and more fast. But there are many technical problems during the green building construction. The Library of Shandong Jiaotong University is the first case of green library building in China. The ecological implementation in the atrium is one of the important ecological strategies of the Library. While construction we encountered more technical problems, especially the contradiction between the natural ventilation, natural lighting and fire safety. In this article based on the atrium technology design of the green building and combined the practice of the atrium some strategies realizing natural lighting, natural ventilation in the fire safety, applicable, economy and art.are summarized in detail. It is the aim to give some references and to promote the green building implementation.

Cfst Columns

‘Concrete Filled Steel Tubes (CFST)’/ ‘Concrete Filled FRP Tubes (CFFT)’ comprises of a steel/ ‘Fiber Reinforced Polymer (FRP)’ hollow pipe of circular or rectangular shape filled with plain or reinforced concrete. Need of such composite columns in the field of building construction is due to advancements in technology, need of bigger space in smaller land area, ease in construction workability, and a lot of other modern time requirements. This paper defines an experimental and computational project carried out by testing a total of 49 CFST columns and 60 CFFT columns. Three Finite Element models were also made using the software pack ABAQUS. Variables for the study were aspect ratio of columns, Shape of columns (i.e. square, circular or rectangular) and material (i.e. steel or FRP). Basic aim of the project was to find structural parameters like load-deflection behaviour, deflection pattern, maximum load carrying capacity etc. The Steel reinforced concrete-filled fiber reinforced polymer (FRP)tubular column is proposed as a new form of composite column to obtain higher mechanical performance. A comparative analysis was also carried out using three main resulting indices like Ductility Index (DI), Strength Index (SI) and Concrete Contribution Ratio (CCR). Comparative observations between CFST/CFFT columns of different shapes and sizes is carried out, also experimental results were compared with analytical results obtained from ABAQUS software.

There are severe issues for the deficiency of affordable house for low-income earners in developing countries such as Nigeria. The high cost of conventional materials has been established to be one the major factors that heightened the cost of building in recent times. However the integration of green building materials that are relevant and sustainable for building construction in the present dispensation will provide excellent solutions to overcome high price of construction. The study was carried out on all the available green materials in north-central Nigeria. Surveyed instrument was prepared and distributed to building professional experts that are registered member of various professional bodies in the building sector. Four hundred questionnaires were distributed in the north-central zone. Three hundred five questionnaires that were filled correctly was used for the data analyses. Analysis of moments (AMOS) software through the structural equation model (SEM) was used to analysis and generated a model for the study. The result discloses that earth bricks, stone/rocks, timber, Bamboo, thatches, straw fibre, and rice husk are very relevant green materials that can be used to achieve affordable building construction. Therefore, the use and integration of green materials in building construction will produce low cost housing units

The Impact

The formwork system (FWS) in reinforced concrete (RC) construction is a critical component. The appropriate FWS is selected based on a number of conflicting and compromising criteria, and the selection of the FWS is carried out by construction professionals with different technical and/or administrative backgrounds. The perspectives and perceptions of construction professionals and companies involved in the FWS selection process may vary depending on their motives. In addition, some building structural parameters may have a significant impact on the FWS selection criteria. Most of the former studies investigated the FWS selection criteria from only the perspective of contractors and neglected the potential differences in the perspectives and perceptions of different construction professionals (i.e., owners (CO), project managers (PM), construction managers (CM), site engineers (SE), planning engineers (PL), procurement engineers (PR), technical office engineers (TO), and formwork design and/or formwork sales engineers (FD/FSL)) and companies specialized in different fields (i.e., project management service (PMS), engineering and design (ENG/DSG), formwork and scaffolding (FW/SCF), and general and/or sub-contractor (GC/SC)) regarding this issue. Moreover, the impact of building structural parameters on the FWS selection criteria has not been investigated. This study aims to fill this knowledge gap through analysing the FWS selection criteria for building construction projects while comparing the perspectives and perceptions of different groups of construction professionals and companies and investigating how FWS selection criteria are affected by the building structural parameters. Based on a comprehensive literature review, 35 FWS selection criteria were identified and a questionnaire was developed. The questionnaire data obtained from 222 Turkish construction professionals were statistically analysed using mean score analysis, the Kruskal–Wallis test, and the Mann–Whitney U test. According to the study’s findings, the FD/FSL group presented significant statistical differences regarding the FWS selection criteria as compared to the CO, PM/CM/SE, and PL/PR/TO groups. Moreover, the total area of building construction and total building height significantly affected the FWS selection criteria. This study serves to underscore the perspectives of various groups of construction professionals and the critical connection between the structural parameters and FWS selection criteria. The findings of this study may guide construction professionals to select the appropriate FWS for their building construction projects.
