Probabilistic Models for the Tensile Properties of Split Boards and Their Application for the Prediction of Bending Properties of Engineered Timber Products Made of Norway Spruce

Buildings, 2022
The main strength and elastic properties of structural timber products, such as glued laminated timber (glulam; GLT) and cross-laminated timber (CLT), are usually described via load-bearing models, which use the tensile properties parallel to the grain ...

GLULAM BEAMS WITH HOLES

Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS, 2014
This paper provides a systematic review of research on glued laminated timber beams with circular and rectangular openings. Experiments on girders with unreinforced openings varied several parameters, including the girder span and shape, opening position and shape, and the relationship between the stress state near the opening and the ratio of opening ...

Study on flexural performance of prestressed glulam continuous beams under control influence

Journal of Wood Science, 2021
Traditional glulam beam connection mode has a weak ability to transfer bending moment, leading to insufficient joint stiffness and mostly in the form of simply supported beams.

BAMBOO-REINFORCED GLULAM BEAMS: AN ALTERNATIVE TO FIBERGLASS-REINFORCED GLULAM BEAMS

Dyna, 2012
Se realizó un estudio experimental para investigar el comportamiento mecánico de vigas de madera laminada reforzadas con fibra de vidrio o bambú. El refuerzo se propone con el fin de mejorar la resistencia en flexión y la ductilidad de las vigas de madera laminada. La viga se refuerza en la zona traccionada y en las caras laterales con los refuerzos de

Multi‐variate seismic fragility assessment of CLT coupled wall systems

Earthquake Spectra, Volume 39, Issue 4, Page 2100-2122, November 2023., 2023
The cross‐laminated timber coupled wall (CLT‐CW) system, a recently proposed timber‐based structural system, has limited understanding of its seismic performance. The existing research in probabilistic seismic fragility assessment (PSFA) of CLT buildings reveals gap, particularly regarding comprehensive evaluation of CLT‐CW systems and the impact of ...

RELIABILITY OF GLULAM BEAMS SUBJECTED TO BENDING

Electronic Journal of the Faculty of Civil Engineering Osijek-e-GFOS, 2016
This paper presents probabilistic reliability analyses of glulam beams by using level I semiprobabilistic procedure according to Eurocode standards and level II first-order reliability method. The analyses were performed for normal design situations on two groups of girders: roof and ceiling girders.

Triaxial shake table testing of an integrated low‐damage building system

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 10, Page 2983-3007, August 2023., 2023
Abstract Lessons from recent earthquakes have provided a tough reality check of the traditional seismic design approach and technologies, highlighting the urgent need for a paradigm shift of performance‐based design criteria and objectives toward low‐damage design philosophy and technologies for the whole building system.
