Structural Timber Design – (incl. ebook as PDF) de W Seim

Structural Timber Design – (incl. ebook as PDF)

Autor W Seim
en Limba Engleză Paperback – 7 mai 2024

Descoperim în Structural Timber Design – (incl. ebook as PDF) o resursă tehnică esențială pentru ingineria modernă a lemnului, un domeniu care cunoaște o expansiune accelerată în construcțiile rezidențiale multietajate și structurile industriale. Considerăm că valoarea principală a acestei lucrări rezidă în modul în care W Seim explică performanța materialelor compozite și derivate, precum CLT (Cross Laminated Timber) și LVL (Laminated Veneer Lumber), adaptate cerințelor actuale de sustenabilitate și viteză de execuție. Ca și Jack Porteous în Structural Timber Design to Eurocode 5, autorul distilează experiență reală în principii acționabile, făcând trecerea de la proprietățile fizice ale fibrei lemnoase la calcule riguroase de proiectare structurală.

Structura volumului este una progresivă și aplicată. Primele capitole fundamentează înțelegerea lemnului ca material anizotrop, detaliind modul în care umiditatea și durata de încărcare modifică rezistența și deformarea. Ulterior, cuprinsul ghidează cititorul prin verificări complexe ale elementelor de tip grindă, abordând nu doar încovoierea și forfecarea, ci și stabilitatea structurală prin metode specifice pentru flambaj și torsiune. Subliniem rigoarea cu care sunt prezentate combinațiile de acțiuni și factorii de modificare, elemente critice pentru siguranța oricărei structuri de lemn.

Spre deosebire de manualele pur teoretice, lucrarea editată de Wiley Vch integrează fenomenele fizice cu cerințele codurilor de practică, oferind o bază solidă pentru ceea ce autorul numește „inginerie creativă”. Este o resursă care echilibrează avantajele greutății reduse și ale prelucrabilității ridicate cu provocările legate de dăunători naturali și comportament higroscopic, oferind soluții de detaliere constructivă indispensabile în birourile de proiectare.

Descriere

Timber construction has been one of the most innovative areas of the building industry for several years. The speed with which new products are introduced into practical application is almost breathtaking compared to the other construction materials in the building industry. As a result, timber construction is continuously increasing its market share in commercial buildings and hall structures, and even in multi-storey construction for residential and office buildings. This book provides essential knowledge and skills required for the design, detailing, and construction of timber structures for typical building structures. Special emphasis is placed on the specific features of timber and wood-based materials compared to other construction materials. This concerns the numerous advantages, as e.g. the comparatively low weight, the good workability of the high-performance material and the large variety of assembling technologies, but also the challenges resulting from the material anisotropy and from the susceptibility to natural pests. In each chapter the essential phenomena are explained first and then brought into connection with code regulations. This aims to support the basic understanding of the interrelations and dependencies in timber engineering, which is the fundamental basis of creative engineering. (Package: Print Book + ePDF)
