Представлен расчет рамной трапециевидной крепи горизонтальной выработки. Расчетная схема крепи является статически неопределимой системой. Решение выполнено методом перемещений. Результаты расчета сопоставлены с полученным ранее решением, выполненным традиционным методом сил. Проведено сравнение трудоемкости решения задачи двумя основными методами. ...
Dieses Buch ist ein praxisorientierter Leitfaden fur die Berechnung und Bemessung von Bruckentragwerken aus Stahlbeton und Spannbeton. Eine 5-feldrige Spannbetonbrucke wird komplett durchgerechnet, wobei die Darstellung uber die einer pruffahigen Statik weit hinausgeht. Alle tragenden Teile, also auch Lager, Talpfeiler und Grundungen, werden berechnet und bemessen, wobei die einzelnen Schritte vertiefend erlautert werden und wertvolle Hintergrun ...
Bearing types and their scope of application are explained in detail and all problems connected with bearings are discussed. The revised new edition takes into account German and European standards. A handbook for design, detailing and construction. ...
The European pre-standard CEN/TS 1992-4 for the design of fastenings by means of headed studs, anchor channels as well as post-installed mechanical and chemical anchors is ready for use. The background and interpretation of the provisions related to the determination of actions and resistances based on limit state design, durability, fire resistance, fatigue and earthquake actions as required by CEN/TS 1992 are described in detail. Selected chap ...
Selected chapters from the German concrete yearbook are now being published in the new English «Beton-Kalender Series» for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn «Beton-Kalender» has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in «ferro-concrete» structures until – as the book's first editor, Fritz von Emperger (1862-1 ...
Design and construction in existing contexts is becoming increasingly important, and often the structures – sometimes of historical interest – can be preserved easily and at minimum cost by employing strengthening measures. Existing concrete members can be strengthened by using adhesives to bond additional reinforcing elements onto or into those members. This book explains the design rules, together with their background, and uses examples to il ...
Beton unterliegt einem Wandel der Anforderungen und entwickelt selbst Innovationskraft mit Auswirkungen auf Gestaltung bis hin zur Baustellenlogistik. Die Entwicklung von hochfesten, ultrahochfesten und selbstverdichtenden Betonen, die gestiegenen Qualitatsanforderungen und die zu erwartende Knappheit naturlicher Gesteinskornungen setzen neue Anforderungsma?stabe an Entwurfskonzepte. Die Anforderungen an die Dauerhaftigkeit von Beton zielen insb ...
Articles about the classic core areas of structural engineering, for example precast elements, composite floors, multi-functional slabs, economic reinforcement in building and industrial and agricultural silo construction. Also: energy storage, fire protection. ...
The durable and economic design of structures today includes not only the verification of structural stability but also of the serviceability for the planned lifetime including the consideration of time-dependent actions and material properties of a structure. ...
