Abstract

Polimer concrete has different behaviour and different mechanic characteristic than others because it depends on material polimer that are used, so that it caused to be researched and be studied its behaviour and mechanic caracteristic.This polimer concrete was made of prepacked system, consisted of unsaturated polyester (UP) added with styrene monomer (SM) as binder matrix, cobalt napthenate solution (CoNp) as a promotor and methyl ethyl ketone peroxide (MEKPO) as an initiator, and coarse aggregate as inclusion. In this composition, variation of polymer concrete based on percentage of polimer and fly ash as a filler, and any other materials were keeped in constant.The object of this research are to find out values of damping (loss factor), dynamic parameter, so that series of laboratory tests were carried out. Test results showed, values of damping (loss factor) 1,669 – 3,017%. Results also showed that much and much more content of polymer caused loss factor (h ), damping coeffisien (c) and damping ratio (x ) decrease, however it showed that fly ash affected to increase value of dynamic parameter.

Abstract

Earthquake is one of the natural disasters that often occurs in Indonesia. One of the effects of earthquake natural disasters is that it can damage building structures. Therefore, the building to be built should take into account the effect of the earthquake load. Planning for a safe multi-storey building must minimize the risk of casualties, especially for health building facilities where there is a lot of human activity. SNI 1726: 2019 is the latest regulation governing the planning procedures for earthquake resistant buildings. In this research, structural modeling software is used to facilitate the analysis to be carried out. The expected results of this study are (1) Comparison of the value of the force in the RSIA Hermina building structure without earthquake loads and with earthquake loads (2) The ability of the RSIA Hermina building structure to withstand the internal forces generated from the analysis using the equivalent static method. From the results of this study, it was found that the increase in moment and latitude values in the beam and column was 2 to 20 times. Meanwhile, the floor slab structure does not experience the impact due to earthquake loads.

Abstract

In general, Self Compacting Concrete (SCC) uses coarse aggreggate with dense graded for mix composition. However, in certain places, sometimes the sources of aggreggate are limited and there’s no stone crusher with possibly use coarse aggreggate with gap graded. H. This research was conducted for investigate the effect of polypropylene fiber additions to SCC with gap graded on workability, compressive strength, splitting tensile strength, and bending strength. Test result for Slump-Flow and T50 for both of gradation with Vf 0%, 0,05%, and 0,1% quilify that Slump-Flow are about 50-65 cm and T50 are 3-15 second. Test result for compressive strength of SCC with gap graded, the optimum Vf is 0,05% with 7,02% increase in strength compared to dense graded with 0% Vf. Test result for split tensile strength of SCC with gap graded, the optimum Vf is 0,05% with 45,53% increase in strength compared to dense graded with 0% Vf. Test result for bending strength of SCC with gap graded, the optimum Vf is 0,05% with 347,28% increase in strength compared to dense graded with 0% Vf.

Abstract

Pengaruh beban gempa dengan dinding geser tidak simetris dipelajari untuk mengetahui kekuatan struktur gedung tersebut terhadap gaya gempa. Penelitian mengambil kasus Gedung rawat inap non bedah RSUD Abdul Moeloek Bandar Lampung 4 lantai dengan meninjau peningkatan momen dan geser dengan mempertimbangkan dimensi dan tulangan pada pelat, kolom dan balok. Gedung memakai dinding geser pada salah satu ujung pada lantai 1 dan 2. Perhitungan beban gempa menggunakan metode statik ekuivalen dan data diolah dengan metode outlying. Momen dan geser pada kondisi tanpa gempa dan dengan gempa dibandingkan. Penelitian ini dibandingkan dengan hasil penelitian (Prayuda et al., 2020)⁠ yang meneliti pengaruh gempa pada Gedung 12 lantai dengan dinding geser terletak di tengah bangunan dan terpasang dari lantai 1 s.d 12. Hasil penelitian ini adalah momen kolom mengalami kenaikan 222.5%, gaya geser 242.25% saat menahan gempa. Peningkatan momen dan geser berturut-turut 5 kali dan 3 kali lebih besar daripada penelitian (Prayuda et al., 2020)⁠. Kenaikan momen dan geser kolom di dekat ram berturut-turut mencapai 1153% dan 780%. Simpangan antar lantai arah x di bawah simpangan izin kecuali kolom 5’ yaitu kolom pada bangunan tambahan; sedangkan simpangan arah y untuk lantai 2, 3, 5 dan 5’ yaitu lantai yang tidak memiliki dinding geser melebihi simpangan izin. Simpangan yang sangat besar terjadi pada bangunan tambahan baik arah x maupun y. Perubahan simpangan yang besar antar lantai, dapat menyebabkan lantai tersebut terpotong bila terjadi gempa besar. Perubahan gaya geser menyebabkan balok dan kolom yang semula aman menjadi tidak aman, sehingga perlu dilakukan penambahan dimensi atau penggunaan perkuatan struktur.
