Most of the soil conditions in Kubu Raya Regency are soft and peat with low carrying capacity potential for foundation subsidence, especially high-rise buildings. Using a Hydraulic Static Pile Driver 120 tons Crane Mounted Drop Hammer 35 is an alternative to driving deep foundations on soft/peat soils. The purpose this study was conduct comparative productivity, costs, risk aspects, occupationa...

A new type of precast pile, namely steel strand square piles with reinforcement (PRS), is proposed in present study, which uses as a prestressed and equipped hot-rolled reinforcement. Two kinds full-scale pile specimens different were constructed to study the bending performance by tests. The finite element model was also performed differences resistance, deformation capacity, crack failure mod...

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...

In the precast structures, optimization of structural elements is of great interest mainly due to a more rationalized way that elements are produced. There are several elements of precast prestressed concrete that are objects of study in optimization processes, as the prestressed joist applied in buildings slabs. This article inquires into cost minimization of continuous and simply supported sl...

We review the transition now being undertaken from 2D drafting to 3D parametric modeling and the development of Building Information Modeling (BIM). We examine the functionality of BIM platforms, using an example from precast concrete structures. We formulate the development of parametric modeling of building systems from the context of SFB modeling and characterize most parametric modeling as ...

Impact tests were conducted using a specially made drop hammer impact device on concrete specimens (C60–C90) containing lean iron ore from mine waste as coarse aggregate to realize enhanced resistance in applications such pile driving. also equivalent conventional limestone for comparison. The statistical analysis results show that the number of impacts at initial and final cracking conformed W...

The structural integrity of precast concrete buildings depends mainly on the connections between the precast structural components. Large precast concrete panels are used extensively in North America for low, medium, and highrise construction due to their ease and speed of assembly, and high quality control. This paper presents the results of twenty-two prototype specimens tested to investigate...

Devising the most appropriate testing strategy and conceiving a mock-up “as simple as possible, but not simpler” is the challenge which has to be taken whenever a research programme does involve experiments. Optimizing the experimental programme reduces the risk of either wasting time and resources or missing some of the fundamental ingredients of the structural behaviour because of oversimplif...

The prestressing force is transferred to the concrete during the slack period of precast concrete structures fabrication. To contribute to a better understanding of the armor compliant behaviors during the mentioned process, a custom quasidistributed Bragg Grating optical fiber sensor system is designed, fabricated and embedded into a prestressed concrete prismatic beam. The experimental works,...
