Evaluation of post tension runway plate as retrofitting simulated with compression in-plane force in numerical approach / Muhammad Daffa Fachrur Reza, Sofia W Alisjahbana and Muhammad Nuzulul Furqan

The swelling of soil can result from fluctuations in its moisture content, causing it to expand and contract. To mitigate this, structures in direct contact with the soil may require retrofitting. Post-tensioning is one such method that can enhance the stiffness of the structure without altering its...
