Bu çalışmada üç parametreli zemin modeli kullanılarak elastik zemine oturan tabakalı ortotrop plakların hareketli yükler altındaki davranışı incelenmiştir. Yapılan analizlerde SAP2000 ve MATLAB paket programları eş zamanlı kullanılmıştır. Bu amaçla MATLAB ortamında OAPI fonksiyonlarını kullanan bir yazılım kodlanmıştır. Oluşturulan çözüm modeli literatürden alınan bir örnek üzerinde doğrulandıktan sonra laminasyon şeması, laminasyon açısı, tabaka sayısı zemin derinliği, zemin elastisite modulü, plak kalınlığı ve hareketli yükün hızı gibi parametrelerin plağın davranışı üzerindeki etkileri araştırılmıştır. mıştır.  Çalışmanın sonunda OAPI fonksiyonların kullanılmasıyla geliştirilen çözüm yönteminin bu tür karmaşık problemlerin çözümünde güvenilir ve pratik bir şekilde kullanılabileceği ortaya çıkmıştır.

Modelling Laminated Orthotropic Plate-Foundation Interaction Subjected to Moving Load Using Vlasov Model

Öz

In this study,
dynamic behavior of laminated orthotropic plates on elastic foundation is
investigated adapting the three parameter subsoil model. Analysis of the system
is performed by using SAP2000 combining with MATLAB code for calculation of
soil parameters of modified Vlasov model. A computing tool is coded in MATLAB for
the purpose allowing data exchange simultaneously between SAP2000 and MATLAB
via Open Application Programming Interface (OAPI) feature. The consistency of
the proposed model is shown comparatively with a numerical example taken from
the literature. Later, the effects of lamination scheme, various lamination
angles, lamination number, subsoil depth, elasticity modulus of subsoil, plate
thickness and velocity of moving load on the behavior of laminated orthotropic
plates on elastic foundation are investigated. It can be concluded that it is
really convenient to use OAPI feature of SAP2000 to model this complex behavior
of laminated orthotropic plates on elastic soil under moving load.
