A review of a uniquely designed floated jack-up concrete slab to isolate fourteen movie theaters on multiple floors within a multi-use building. The jack-up boxes were engineered and custom tailored to increase airborne sound transmission loss performance while achieving a very high vibration isolation efficiency specified. Field test results were obtained to validate the floating jack-up concrete's acoustical performance.

Reinforced Concrete Wall

Reinforced concrete wall subjected to an impact by a hard steel missile with a mass of 47 kg and an impact velocity of 135 m/s was one case study in the IRIS 2010 benchmark exercise in OECD/NEA/CSNI/IAGE framework. The wall had dimensions of 2m × 2m × 0.25m and it was simply supported. The perforation of the missile was expected. Fortum Power and Heat Ltd. participated in the benchmark. In this paper, we present our modeling and blind prediction of the benchmark case. The test results of the benchmark were released after the predictions were made. Based on the result comparison, we concluded that our model gave conservative results.

<p><strong>Abstract:</strong> This study aims to produce guidance products that have acceptance criteria. The type of research used is development using the research design of Borg and Gall. The stages used in this research are information gathering, planning, initial field testing, developing the initial product format, product revision, main field testing, and product revision or refining the main field test results. The data obtained in the form of quantitative data with the gregory model interrater agreement. The subjects in the field test consisted of two BK experts, two media experts, and two potential product users. The assessment conducted by the expert refers to the criteria for product acceptance which includes aspects of accuracy, aspects of usability, and aspects of eligibility. Based on the results of the field test the assessment results obtained from BK experts have a validity index of 0.73 which is categorized as "high", the assessment of media experts is 1.00 which is categorized as "very high", and from potential users that is 1.00 which is categorized as "very high ", so it can be concluded that the guidelines developed meet the product acceptance criteria.</p><strong>Abstrak:</strong> Penelitian ini bertujuan menghasilkan produk panduan yang memiliki kriteria keberterimaan. Jenis penelitian yang digunakan adalah pengembangan menggunakan rancangan penelitian Borg and Gall. Tahapan yang digunakan dalam penelitian ini adalah pengumpulan informasi, perencanaan, uji lapangan awal, pengembangan format produk awal, revisi produk, uji lapangan utama, dan revisi produk atau penyempurnaan produk hasil uji lapangan utama. Data yang diperoleh berupa data kuantitatif dengan <em>interrater agreement model gregory</em>. Subjek dalam uji lapangan terdiri dari dua ahli BK, dua ahli media, dan dua calon pengguna produk. Penilaian yang dilakukan ahli mengacu pada krtiteria keberterimaan produk yang mencakup aspek ketepatan, aspek kegunaan, dan aspek kelayakan. Berdasarkan hasil uji lapangan diperoleh hasil penilaian dari ahli BK memiliki indeks validitas sebesar 0,73 yang dikategorikan “tinggi”, penilaian dari ahli media yaitu 1,00 yang dikategorikan “sangat tinggi”, dan dari calon pengguna yaitu 1,00 yang dikategorikan “sangat tinggi” sehingga dapat disimpulkan bahwa panduan yang dikembangkan memenuhi kriteria keberterimaan produk.

Undrained Shear

The objective of this paper is to compare field test results obtained in a stiff sensitive clay from Quebec using prebored, instrumented sharp cone tests (ISCTs) with those deduced from prebored and self-boring pressuremeter tests (PMTs and SBPMTs, respectively) and vane shear tests (VSTs). Comparisons are also made with triaxial test results. It is shown that undrained shear strengths Su deduced from PMTs and ISCTs are greatly overestimated with respect to the values inferred from SBPMTs and VSTs. As for the shear modulus G, the opposite is true. These discrepancies are considered to arise from initial disturbance and unloading caused by drilling of pilot holes in the case of PMTs and ISCTs. Interpretation problems may be also related to the existence of very high lateral pressures at rest in the clay deposit.

Concrete Testing

In this paper a case study about concrete strength assessment of bridge structure experiencing fire is discussed. Assessment methods include activities of visual inspection, concrete testing by Hammer Test, Ultrasonic Pulse Velocity Test, and Core Test. Then, test results are compared with the requirement of RSNI T-12-2004. Test results show that surface concrete at the location of fire deteriorates so that its quality is decreased into the category of Very Poor with ultrasonic pulse velocity ranges between 1,14 – 1,74 km/s. From test results also it can be known that concrete compressive strength of inner part of bridge pier ranges about 267 – 274 kg/cm2 and concrete compressive strength of beam and plate experiencing fire directly is about 173 kg/cm2 and 159 kg/cm2. It can be concluded that surface concrete strength at the location of fire does not meet the requirement of RSNI T-12-2004. So, repair on surface concrete of pier, beam, and plate at the location of fire is required.
