COMPARISON TRADITIONAL SYSTEMS OF TUNNEL FORMWORK SYSTEM

Abstract

Tunnel formwork systems became the most widespread construction technology preferred in recent years in Turkey due to rapidity and economy. In this study, before all else, a brief information was given about the types and construction techniques of tunnel formwork systems. Then a reinforced concrete building sample was firstly modeled as it was constructed with the tunnel formwork system and secondly modeled as it was formed by a frame system with shear walls constructed by the traditional reinforced concrete construction technique. Both models were solved using SAP-2000 computer program and compared with each other in terms of floor displacements, base shear forces and periods. Additionally, the construction costs of both tunnel formwork and traditional formwork systems were examined and compared with each other in terms of construction speed and cost. As a conclusion, the evaluation of both systems was made according to the obtained data and the application suggestions were given.

TÜNEL KALIP SYSTEMLERYN GELENEKSEL SYSTEMLERLE KAR?ILA?TIRILMASI

Öz

Tünel kalyp sistemler, ülkemizde özellikle son yyllarda gerek süratli olmasy gerekse ekonomik olmasy nedeniyle yaygyn olarak tercih edilen yapym teknolojilerinden biri haline gelmi?tir. Bu çaly?mada öncelikle tünel kalyp sistemlerin türleri ve yapym teknikleri hakkynda kysaca bilgi verilmi?tir. Daha sonra, örnek bir betonarme bina ilk olarak tünel kalyp sistem ?eklinde modellenmi? daha sonra ayny betonarme bina geleneksel yapym tekni?i ile perdeli çerçeve sistem ?eklinde dü?ünülüp modellenmi?tir. Her iki sistemin de Sap-2000 programynda çözümü yapylmy? ve kat deplasmanlary, taban kesme kuvvetleri ve periyotlary yönünden kar?yla?tyrmalar yapylmy?tyr. Ayryca tünel kalyp sistem ve geleneksel kalyp sistem yapym maliyetleri açysyndan da incelenerek, her iki sistem yapym maliyeti ve imalat hyzy açylaryndan kar?yla?tyrylmy?tyr. Sonuç olarak elde edilen veriler do?rultusunda her iki sistemin de?erlendirilmesi ve uygulama önerileri verilmi?tir.
