The zaojing: review of a unique wooden construction typology

Corentin Jean Dominique Fivet, Jingxian Ye

The zaojing is an ancient Chinese construction system consisting of a dome-shaped assembly of interlocked wooden pieces. These structures are placed above live performance spaces to enhance sound diffusion while creating background scenery. Existing zaojin ...

Mechanical properties of a balsa wood veneer structural sandwich core material

Thomas Keller, Anastasios Vassilopoulos, Niloufar Vahedi

Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One a ...

Reconsidering traditional timber joinery for sustainable structures

Corentin Jean Dominique Fivet, Jan Friedrich Georg Brütting

Timber construction plays an important role in architectural history, in modern construction methods and in sustainable design, for which wood-only joinery techniques have been used for centuries. Traditional joinery typologies are the product of successiv ...

Connection systems between composite sandwich floor panels and load-bearing walls for building rehabilitation

Thomas Keller, Mário Alexandre De Jesus Garrido

The use of advanced composites for building rehabilitation presents several advantages when compared with traditional construction materials. When degraded building floors need to be replaced, composite sandwich panels are a potentially interesting solutio ...

Adhesively bonded connections between composite sandwich floor panels for building rehabilitation

Thomas Keller, Mário Alexandre De Jesus Garrido

A connection system between adjacent sandwich panels for use in building floor rehabilitation, consisting of an adhesively (epoxy) bonded Z-joint, is proposed and studied. Experimental and numerical investigations were carried out to assess the joints' beh ...

CNC-fabricated dovetails for Joints of Prefabricated CLT Components

Yves Weinand, Christopher Werner Matthias Robeller, Benjamin Hahn, Paul Mayencourt

The widely available automated prefabrication in timber construction companies, as well as modern CAD software with application programing interfaces, allow for the design and production of increasingly geometrically complex building components. This devel ...

Analytical modeling of local stresses at Balsa/timber core joints of FRP sandwich structures

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

In order to optimize sandwich structures, core materials of different density and thus different stiffness and strength are often combined. The material discontinuities at joints of dissimilar core materials may lead to abrupt changes of the shear angles a ...

Elsevier2014

Shear mechanical characterization of balsa wood as core material of composite sandwich panels

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

An experimental study was performed using Iosipescu specimens to evaluate the effects of parameters such as shear plane, density and adhesive joints on the shear stiffness and strength of balsa wood panels as well as the variation of ductility with respect ...
