Abstract
Many buildings in Spain constructed with "pitch pine" beams are, nowadays, under rehabilitation processes. In some cases the decision on maintaining, or not, the existing timber structure is a key issue. The commercial name “pitch pine” comprises several species in the group of Southern Yellow Pines, being the “Longleaf pine”...

Abstract
Building using cross-laminated timber (CLT) began in Europe about two decades ago and has used a variety of methods for structural analysis. Experimental testing methods were the most accurate, yet they lacked versatility because changes in lay-up, material, or even manufacturing methods could cause a need for new testing. Consequently, three analytical approaches have been created and are commonly used in Europe as none have been universally accepted to date. ... In the United States and Canada, the product standard (Standard for Performance-Rated Cross-Laminated Timber - ANSI/APA PRG 320) has adopted the Shear Analogy method to derive composite bending and shear stiffness properties.

Abstract
This study aimed to investigate the durability of structural laminated veneer lumber (LVL) during outdoor use. We subjected LVL to outdoor exposure tests for 48 months; the tests were designed under the assumption of outdoor use such as temporary enclosure plates used in the construction field. The surfaces of the LVL specimens...
