The dead load nominal moment is 126kNm (SLS Gamma= 1.0) and the live load moment is 254kNm (SLS Gamma= 1.0). When the section is attached to the cast in place slab the Neutral axis is forced to be horizontal.Check the crack widths for this design situation using the SLS Frequent Combination of actions (not normally a requirement for this design situation but shown for completeness).Check that the concrete and steel stresses do not exceed the SLS limits using the characteristic combined capacity. The precast beam is lifted at its ends through the centroid of the section which generates a nominal My bending moment of 218kNm due to the dynamic effect on its self weight.The calculation of Serviceability limit state stresses and maximum crack widths are to be calculated for the edge section, with reinforcement defined in section 3, under two load/design situations. Interpolation between long and short term modulus.For a birds-eye view of the ice fields and glaciers, try our optional flight-seeing tours. Some of our itineraries can include a visit to Tracy Arm Fjord, home of the twin Sawyer Glaciers. Below that, the ice is more solid and the pressure greater, creating a more intense blue color. The upper 100 feet of a glaciers depth is brittle and deep cracks called crevasses form on the surface. Towards the terminus of the glacier more ice is lost than accumulates so the glacier forms great folds and deep cracks, like rapids in a river. Glaciers follow the path of least resistance, occupying stream valleys. As layers of ice accumulate at the top of a mountain, the pressure increases and they start to move downhill. Glacial ice appears blue due to the physical characteristics of water molecules which absorb all colors except blue which is reflected. These crystals meld with others to form dense glacial ice, one layer for each year. Snowflakes are transformed to granular ice crystals in the summer months. Simply put, glaciers occur when snow accumulation is greater than the melt. Just as you hear a huge crack, like the sound of cannon fire echoing through the fjord, a spire of ice falls into the water sending a splash 200 feet into the air. We wait patiently for a house-size chunk to break from the face. Imagine a beautiful, blue-sky morning floating amongst ice bergs at the face of a mile-wide glacier in Tracy Arm Fjord. Alaska Sea Adventures is one of very few if not the only option to visit here in winter. A winter visit to South Sawyer Glacier in Tracy arm provides an incredible contrast from that encountered with during a summer visit.
