  • Increase in use of deck plates is accelerated by a manpower shortage and the high cost of construction. Some of problems including fire resistance, waterproof, and low corrosion can be solved by development of new deck plates. This paper evaluates the structural performance of the LAMO Deck which metal laths instead of galvanized steel sheet is covered by mortar.

  • In the domestic construction industry field nowadays, the usage of deck plates is currently increasing due to the lack of construction workers and the rised in construction cost. However, using deck plates manufactured by thin zinc galvanization in underground structures is criticised because it can lead to increase in maintenance cost caused by rust generation and water leakage. As a solution for this particular problem, deck plates created by Lath and Mortar instead of zinc galvanized steel sheets were developed. This paper deals with the experimental study on flexural behavior of deck plate using metal lath and mortar. Seventeen fullscale specimens were constructed and tested with different type of truss, the diameter of the top and bottom bar, and the thickness of slab. Tests results show that LAMO deck displayed equal performance such as zinc galvanized steel sheets.
