WEBINAR HAKI KOMDA YOGYAKARTA : CONCRETE TECHNOLOGY ON EARTHQUAKE RESISTANT STRUCTURE
On 9 February 2023, PT. Geoforce Indonesia, represented by the main director, Mr. Dandung Sri Harninto, had the opportunity to be one of the speakers at the WEBINAR HAKI KOMDA YOGYAKARTA : CONCRETE TECHNOLOGY ON EARTHQUAKE RESISTANT STRUCTURE. This Webinar event is a collaboration between HAKI KOMDA YOGYAKARTA and SIPILPEDIA ACADEMY. There are several discussions in this Webinar, including:
- Fiber Concrete by Prof. Ir. Iman Satyarno, ME., Ph.D.
- Requirements for Reinforced Concrete Materials for Earthquake Resistant Buildings by Prof. Ir. Iswandi Imran, M.A.Sc., Ph.D.
- Lightweight Concrete and Its Application on Precast Slabs as an Effort to Reduce Earthquake Loads in Buildings by Prof. Ir. Bambang Suhendro, M.Sc., Ph.D.
The material discussed by Mr. Dandung Sri Harninto is Earthquake Resistant Local Precast Concrete Segmental Retaining Walls With Geosynthetic Reinforcement. In his material presentation, Mr. Dandung gave a brief description of the company Geoforce Indonesia, Challenges for Increasing Local Products, Challenges for Retaining Walls, Geosynthetic DPT Design Process and Solutions using GSRW and GBRW.
Geoforce Segmental Retaining Wall (GSRW) is a retaining wall construction consisting of segmental facing precast concrete, compacted embankment layers, and a GI-Strip belt reinforcement system (made in Indonesia). Meanwhile, we call precast facing walls with smaller dimensions as Geoforce Block Retaining Walls (GBRW). The facing of the GSRW and GBRW walls is made of precast concrete which is printed with high accuracy. Therefore, the use of GSRW is considered to be far more effective, efficient and economical because it uses relatively thin panels and a lighter structure.
