Abstract

Temperatura in z njo povezane obtežbe predstavljajo poseben izziv inženirjem, saj je temperatura neotipljiva in si jo je težko fizično predstavljati. Zraven tega je vpliv temperature v naravi lokacijsko in časovno spremenljiv. Iz tega vidika je analiziranje in upoštevanje temperaturne obtežbe na matematičnih računskih modelih kompleksno in časovno ter računsko obsežno. Glavni cilj diplomskega dela je bil predstaviti kompleksnost temperaturnih obtežb ter oblikovati obtežno shemo, ki bi se približala stanju v naravi in hkrati opisala zadostno natančnost in zahtevnost glede pogojev standarda SIST EN 1991-1-5, na koncu pa pripomogla k zmanjšanju mest koncentracij upogibnih momentov na kritičnih mestih konstrukcije. Raziskava je pokazala, da je z redukcijo in opuščanjem določenih temperaturnih obtežb na posameznih konstrukcijskih elementih mogoče doseči željene rezultate. V sklopu te raziskave smo ugotovili, da je mogoče temperaturno obtežbo upoštevati na zasutih konstrukcijskih elementih na drugačen način in pri tem še vedno ohraniti bistvene značilnosti iz veljavnega standarda SIST EN 1991-1-5. Namesto referenčne temperature zraka je bila uporabljena referenčna temperatura zemljine.

Secondary title:	Analysis of temperature load on a reinforced conrete bridge frame structure
Secondary abstract:	Temperature and temperature-related loads are intangible and physically very difficult to imagine. Due to these factors, they represent a unique challenge to engineers. In addition, temperature effects vary in location and time, causing the analysis of temperature load in mathematical calculation models to be very complex and time-demanding. The main objective of this work was to represent the complexity of temperature loads and design a loading scheme that would imitate the natural condition while meeting the accuracy and level of difficulty required by the current standard SIST EN 1991-1-5. They would also help reduce the concentrations of bending moments at critical points in our structure. Research has shown that we can achieve our goals by reducing or ignoring certain temperature stresses. During this research, we found that we can consider the temperature loading of buried structural members differently and still maintain the basic requirements of the SIST EN 1991-1-5 standard. Instead of using the air temperature as the reference temperature, we took the earth temperature as the reference point.
