The earthquake that occurred on 7 December 2016 with a magnitude of 6.4 SR in Pidie Jaya District, Aceh has resulted in many material and immaterial losses. Where many facilities and infrastructure are damaged, buildings are not multi-storey to high-rise buildings. One of them is a residential area around the At-Taqarrub mosque, which is in the Keude area, Trienggading sub-district, Pidie Jaya district. At-Taqarrub Mosque is one of the worship facilities that is heavily damaged and cannot be repaired. In the area only the At-Taqarrub mosque was the only building that collapsed, while the surrounding buildings were still standing with various kinds of damage. This journal is to find out the results of rapid assessment of the level of damage to buildings against structures and building materials around the At-Taqarrub mosque. The method used is the method of mapping and direct survey of the surrounding buildings and then determine the level of damage to the structural components and building architecture. The results of this study indicate various levels of post-earthquake building damage that occur and provide recommendations for buildings damaged in the earthquake in Pidie Jaya in particular and throughout Indonesia in general.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

Mass Timber

Abstract Mass timber building materials such as cross-laminated timber (CLT) have captured attention in mid- to high-rise building designs because of their potential environmental benefits. The recently updated multistory building code also enables greater utilization of these wood building materials. The cost-effectiveness of mass timber buildings is also undergoing substantial analysis. Given the relatively new presence of CLT in United States, high front-end construction costs are expected. This study presents the life-cycle cost (LCC) for a 12-story, 8,360-m2 mass timber building to be built in Portland, Oregon. The goal was to assess its total life-cycle cost (TLCC) relative to a functionally equivalent reinforced-concrete building design using our in-house-developed LCC tool. Based on commercial construction cost data from the RSMeans database, a mass timber building design is estimated to have 26 percent higher front-end costs than its concrete alternative. Front-end construction costs dominated the TLCC for both buildings. However, a decrease of 2.4 percent TLCC relative to concrete building was observed because of the estimated longer lifespan and higher end-of-life salvage value for the mass timber building. The end-of-life savings from demolition cost or salvage values in mass timber building could offset some initial construction costs. There are minimal historical construction cost data and lack of operational cost data for mass timber buildings; therefore, more studies and data are needed to make the generalization of these results. However, a solid methodology for mass timber building LCC was developed and applied to demonstrate several cost scenarios for mass timber building benefits or disadvantages.

Wood-based building materials meet the basic requirements of environmentally friendly construction, which is becoming increasingly important in the modern world. However, until recently, they were rarely used in high-rise construction in Russia. CLT became a revolutionary technology, it has proven itself in countries such as Switzerland, Norway, the U.S. and others. In Russia, it has not yet found widespread use, and CLT-panels are in demand only at the market of individual housing construction. Nevertheless, taking into account the positive foreign experience can be an example and become an incentive for more active implementation of modern environmentally friendly materials and technologies in Russia. The aim of the article is to study the possibilities of high-rise wooden house building in Russia based on world practice.

The paper presents new results in the building materials area. One of the solutions of the thin-walled elements obtaining can be achieved due to new additive using. The main purpose of the paper was improvement concrete properties for thin-walled constructive elements. The experimental and standard methods have been used and new complex additive for concrete. The research shows that a comprehensive additive consisting of aqueous solution of polycarboxilate polymer, silica sol and potassium nitrite is effective and makes it possible to produce high-efficiency concrete with unique properties: higher compression strength, higher crack resistance, frost resistance, water resistance, abrasion resistance. The study shows that the concrete is chemical resistant. Modified concrete can be recommended for manufacturing critical concrete structures of special purpose, for example high-rise constriction.

One of the advantages of concrete over other building materials is its inherent fire-resistive properties. The concrete structural components still must be able to withstand dead and live loads without collapse even though the rise in temperature causes a decrease in the strength and modulus of elasticity for concrete and steel reinforcement. In addition, fully developed fires cause expansion of structural components and the resulting stresses and strains must be resisted. This paper reports the results of measurements by Acoustic Emission method during three-point bending test on concrete specimens. The Acoustic emission method is a non-destructive technique used widely for structural health monitoring purposes of structures. The sensors are mounted by beeswax on the surface of the material or structure to record the motion of the surface under the elastic excitation of the cracking sources. The concrete specimens were heated in a programmable laboratory furnace at a heating rate of 5 °C/min. The specimens were loaded at six temperatures, 200 °C, 400 °C, 600 °C, 800 °C, 1000 °C, and 1200 °C maintained for 60 minutes. The results are obtained in the laboratory.

Exposure Risk Assessment

The aim of this work was to study Pb accumulation in indoor dust, and health risk of human due to dust exposure. Risk assessment of Pb to human health: Pb is most harmful to human body. The reasons of non-carcinogenic risk in residential area may be that indoor is not swept regularly, in addition, indoor decoration, building materials and other factors may also affect the content of Pb in dust. Non-carcinogenic risk in children is not only more than adults but also beyond the safety threshold. Indoor dust has been a threat to the health of children in Shenyang.
