Adhesives and metal fasteners have an important place in the content of engineered wood products (EWPs). However, adhesives may cause toxic gas emissions due to their petroleum-based nature, while metal fasteners may adversely affect the reusability of these products. These issues also raise important questions about the sustainability and environmental friendliness of EWPs. Thus, there is still room for a solution that is solid and completely pure wood, adhesive- and metal-connectors-free dovetail wood board elements (DWBEs). There are many studies on the technological, ecological, and economic aspects of these products in the literature, but no studies have been conducted to assess the technical performance of DWBEs. This chapter focuses on DWBEs by proposing various geometric configurations for horizontal structural members in multistory building construction through architectural modeling programs. In this architectural design phase, which is one of the first but most important stages, the proposed configurations are based on a theoretical approach, considering contemporary construction practices rather than structural analysis or mechanical simulation. Further research, including technical performance tests, will be undertaken after this critical phase. It is believed that this chapter will contribute to the dissemination of DWBEs for innovative architectural and structural applications, especially in multistory wooden structures construction.

Adhesives and metal fasteners play important roles in the composition and connections of engineered wood products (EWPs) such as cross-laminated timber and glue-laminated timber in the building construction industry. However, due to their petroleum-based nature, adhesives can cause toxic gas emissions, while metal fasteners compromise the end-of-life disposal and reusability of EWPs. These issues adversely affect the sustainable material properties of EWPs. Numerous studies have been conducted in the literature on the technological, ecological, social, and economic aspects of EWPs in construction with different construction solutions, but no studies have been conducted to evaluate the technical performance of dovetail wood board elements (DWBE) in multi-story or tall building construction. This study focuses on adhesive- and metal fastener-free DWBE as sustainable material alternatives for ecologically sensitive engineering solutions. Various preliminary design proposals are presented for DWBE using architectural modeling programs as an environmentally friendly approach intended for use in the timber construction industry. The research findings are based on a theoretical approach that has not yet been practically tested but is proposed considering existing construction practices that need further investigation, including technical performance tests. It is believed that this paper will contribute to the promotion and diffusion of DWBE for more diverse and innovative architectural and structural applications, particularly in multi-story timber building construction, as one of the key tools in tackling climate change challenges.


The Computer Models Of Buildings That Contain All The Information About Future Facilities, Which Is Called BIM (Building Information Modeling) Technologies, Took An Important Place In Architectural Offices And Architectural Design. By Means Of BIM Technologies, The Main Groups Of Specialists Had A Chance To Collaborate From The Very Beginning Of The Creation Of The Building Model And Its Use Up To The End Of The Design Of The Building. Since The 1960s, Computer Programs Were Mainly For Drawing, But With BIM Technologies, It Is Possible To Present A Virtual Reality Of A Building Process. Since It Is Extremely Important To Select Suitable Software To Perform The Analysis And Design In Building Tasks, With The Existence Of Much-Specialized Software In These Domains, In This Paper, Based On The Investigations Performed Especially For The Last Decade Developments And Added Capabilities, A Guideline For Architects And Engineers Is Presented. In This Regard Many Software Were Evaluated And The Most Useful Used Ones Such As Graphisoft Archicad, Autodesk Revit Architecture, Gehry Tech., Nemetschek Allplan Architecture, TAD, Nemetschek Vectorworks Architect, Digital Project Designer, Microstation, Dynamo Studio, Freecad Architecture, Sketchup Software Are Recommended To Be Employed In Analysis And Design Of Buildings. Employing The Recommended Software, Not Only Facilitate The Teamwork In Design But Also Increase The Performance Of The Design

Abstract High-rise buildings in big cities are crucial for business, economic, educational, residential, and entertainment activities in recent times. The technology discoveries in various fields that support high-rise building construction such as structure, mechanical, electrical, and materials have opened up opportunities for comfortable and environmentally safe architectural work. The first milestone of high-rise building construction knowledge in Indonesia was the completion of the thirteen-floors Sarinah retail building in 1967. Indonesia, especially in Jakarta, then experienced rapid growth of high-rise buildings construction. However, there is limited research on the development of high-rise building designs in Indonesia, especially from an architectural design perspective. It leads to the lack of literature on high-rise building design in Indonesia. By utilizing a publicly accessible database from the Council of Tall Buildings and Urban Habitat and recent literature called Designing Tall Building by Mark Sarkisian, this paper explores the design development of high-rise buildings in Jakarta from time to time in the aspects of architecture, structure and sustainability.

The use of environmentally friendly building materials has experienced slow growth within the residential construction market due to higher cost and low availability of certified wood. The development of green building programs (GBPs) marked the beginning of the effort to adopt energy-efficient design guidelines and utilize eco-friendly renewable materials in structures. These programs were targeted at reducing environmental impacts by integrating eco-friendly materials into the design and construction of buildings, including promoting the use of environmentally certified wood products (ECWPs) harvested from sustainably managed forests. This research was designed to determine which attributes influence architects’ decisions to use environmentally certified wood products in residential construction projects and how this might influence their perceptions and use of green building programs. The results indicate that architects who have participated in a GBP were more likely to have used ECWPs. The material attributes that influence architects’ selection of materials are mainly related to economics and function as opposed to environmental friendliness. These results will help to inform and broaden the understanding of issues that influence the adoption and utilization of environmentally certified wood products, and identify some of the factors that can contribute to their continued growth in the U.S. marketplace.

Wood belongs among one of the oldest building materials in Slovakia. Historically, it has been used mainly in traditional folk architecture, however in many forms; as a structural and expressive material, it is an inherent part of representative historical architecture. Considerable decline in the use of wood as structural material started in the 2nd half of the 20th century, when building construction industry turned to more progressive materials such as concrete, steel, aluminium, plastics and glass.

Adaptive kinetic architecture has emerged from a need for innovative designs that adapt to the environment and changing needs of the occupants. Architectural design and modes of egress are critical in an emergency. Flocking describes a certain collective behavior where agents are brought together in groups and move as a cohesive unit from place to place. Collective behavior may be observed in microscopic as well as macroscopic environments. Crowd modeling incorporates the study of human behavior, mathematical modeling, and molecular or fluid dynamics. The simulation of agents and their movement in the built environment is beneficial for design professionals, scientists, and engineers. Human behavior in panic situations is notably similar to fluids and molecules. The objective of this research was to evaluate the movement of agents in buildings using discrete dynamic simulation. We used a novel discrete molecular dynamics technique to simulate the evacuation of agents in panic situations. Various adaptive geometric configurations were analyzed for improved crowd flow. Kinetic walls were modeled in order to evaluate design optimization as it relates to rates of egression. This research proposes the use of kinetic walls to improve safety and efficiency during an emergency evacuation. Adaptive geometric configurations show improvements over the conventional design framework.
