Improving the prediction of strength and rigidity of structural timber by combining ultrasound techniques with visual grading parameters

open access: yesMateriales de Construccion, 2007
The present study explores the possibility of using longitudinal ultrasound transmission to evaluate the bending strength and modulus of elasticity in structural timber made from the two species most commonly found in Spanish construction and ...

Abstract of: Experimental Investigation of Mortar Mechanical Properties for Glass Brick Masonry

open access: yesChallenging Glass Conference Proceedings, 2018
The main advantage of solid bricks over hollow blocks is substantially higher compressive strength. On the other hand, solid bricks have much higher thermal conductivity, which would lead to major heat loss when used for exterior walls.

In-situ density estimation by four nondestructive techniques on Norway spruce from built-in wood structures [PDF]

open access: yes, 2018
Needle penetration resistance (NPR), screw withdrawal resistance (SWR), core drilling (CD) and drilling chips extraction (DCE) are nondestructive and semi-destructive techniques used to estimate density in timber structures.

Four-point bending tests of PVB double laminated glass panels – experiments and numerical analysis

open access: yesChallenging Glass Conference Proceedings, 2020
Current architecture uses glass even for load bearing structural elements. Typical example is perpendicularly loaded laminated glass panel as a part of balustrade, staircase, or canopy.

Cross-Laminated Timber: A Survey on Design Methods and Concepts in Practice

open access: yesCivilEng, 2022
Cross laminated timber (CLT) is becoming increasingly popular in timber construction due to its versatility. However, its structural anistropy requires the application of particular concepts and design methods. The article on hand presents the results of

Mechanical behaviour of timber‐to‐concrete connections with inclined screws

open access: yesJournal of Civil Engineering and Management, 2007
The purpose of this paper is to adopt the Johansen's yielding theory as a possibility to predict the ultimate load for timber‐to‐concrete joints using self‐tapping threaded connectors screwed at an angle into the wood.

Implementation of longitudinal welding stresses into structural calculation of steel structures

open access: yesJournal of Civil Engineering and Management, 2015
During welding of typical steel cross sections, like T or I- Profiles e.g., residual stress occurs and need to be considered during the design process.

Comparison of behaviour of laterally loaded round and squared timber bolted joints [PDF]

open access: yes, 2016
In the current European standards for design of timber structures, the issue of timber-to-timber joint type is addressed only to squared timber, which makes the pinpointing of the round timber bolted joints load carrying capacity near-unfeasible due to ...
