Abstract

Building construction in the Soloraya area often encounters cracking problems. This problem is generally caused by various factors such as improper design, poor material quality, building age, etc. which can have an impact on durability and structural strength. Therefore, Appropriate Structure Research Group conducted a community service with the aim of providing solutions to be utilized in the construction of buildings in the Soloraya area. This service was carried out with CV. Sokogi Reksacipta which is a local construction consultancy service provider. The concrete innovation presented as a solution is hybrid fiber concrete that combines natural fibers, i.e. ramie fibers and synthetic microfibers with improved mechanical properties to increase resistance to cracking. Through a series of laboratory tests and data analysis, the effectiveness of using hybrid fiber concrete in reducing the risk of cracking and increasing the durability of concrete structures was evaluated. The method used in this community service is socialization of the use and method of making innovative concrete. From the results of this program, 93.75% of participants understood the socialization activities, therefore this program is expected to contribute to the development of more durable and sustainable concrete technology for building construction applications in the Soloraya area.

Abstract

The pile foundation is the lower building structure that supports the above structure. Pile foundations withstand combined loads from the vertical and horizontal directions. In the field, both loads work simultaneously. However, in Indonesia, in general, the axial and lateral loading tests are carried out separately. Related to this, there have been few investigations on the influence of combined loads on pile foundations. These led to inconsistent results to the effects of adding the axial load on the lateral loading. The three-dimensional finite element method is used in this study to analyze the effect of vertical displacement on a single pile foundation with the additional axial loads on lateral loads. Two pile foundation models were made, the first pile foundation model is a single pile foundation without a pile cap, while the second pile foundation model is modeled with a pile cap. Two models were applied by the lateral load with the additional variation axial load of 0H, 0.25H, 0.5H, 0.75H, and 1H. The vertical displacement is significantly decreased in the pile foundation model with a pile cap compared to the pile foundation model without a pile cap. The reduction in vertical displacement of pile foundations with a pile cap due to the addition of axial loads affects up to 30%, 24%, 19%, 16%, 14% of pile foundations without a pile cap, respectively. This research is expected to help decision making consideration in the design and planning for pile foundations.
