Cap18

struct DLResult

A result from the Table4A table (just one entry).

Fields

• sta::Int - station along bent
• dist::Float64 - actual distance along bent
• defl::Float64 - deflection of bent at station
• moment::Float64 - moment of bent at station
• shear::Float64 - sheat of bent at station

struct Envelopes

A result from Table6 table (just one entry).

Fields

• sta::Int - station along bent
• dist::Float64 - actual distance along bent
• max_moment::Float64 - envelope of max positive moment
• min_moment::Float64 - envelope of max negative moment
• max_shear::Float64 - envelope of max positive shear
• min_shear::Float64 - envelope of max negative shear

struct Header1

Contains project information needed to run Cap18.

Fields

• file_num_5::String = "00001" - file number for the project (5 slots available)
• county_13::String = "___County____" - county for the project (13 slots available)
• hwy_num_6::String = "Highwy" - highway number for the project (6 slots available)
• proj_num_4::String = "Pro#" - project number (4 slots available)
• csj_11::String = "0000-00-000" - CSJ for the project (11 slots available)
• coded_by_3::String = "BRG" - Initials of originator (3 slots available)
• date_12::String = "" - date (12 slots available)
• comment_7::String = "Comment" - additional comment (7 slots available)

Examples

julia> h1 = Header1()
Header1("00001", "___County____", "Highwy", "Pro#", "0000-00-000", "BRG", "", "Comment")

julia> write(h1) # this writes header info to the .dat file
 

struct Reactions

A result from Table7 table (just one entry).

Fields

• sta::Int - station along bent
• dist::Float64 - actual distance along bent
• max_reaction::Float64 - maximum reaction at support
• min_reaction::Float64 - minimum reaction at support

struct StiffnessLoadData

A result from Table4 table (just one entry). Loads input as Cap and Stringer loads are applied directly to the cap. Loads input as Slab and Sidewalk Loads and Moving Loads are transmitted to the cap through the stringers, if any. Concentrated overlay loads are applied directly to the cap while distributed overlay loads are automatically transmitted to the cap through the stringers.

Fields

• sta_from::Int - starting station
• sta_to::Int - ending station
• contd::Int -
• cap_bending_stiffness::Float64 - bending stiffness of the cap (kip*ft^2)
• sidewalk_slab_loads::Float64 - sidewalk load (transmitted through stringers)
• stringer_cap_loads::Float64 - stringer loads
• overlay_loads::Float64 - overlay loads
• movable_position_slab_loads::Float64 - movable loads

struct Table4A

Table4A of the Cap18 analysis results.

Fields

• results::Vector{DLResult} - collection of the dead load results from Table4A

change_string_by_slicing(original_string, start_index, end_index, new_substring)

A function to change parts of a string by slicing. This returns a new string. It is strict. The start and ending index range of the string will be replaced with the same number of characters. The function will error if more characters are given than the range provided. It will fill the left side of the range with spaces if the substring is smaller than the range provided.

Parameters

original_string - original string to modify start_index - index where modification starts end_index - index where modification ends new_substring - substring which will be inserted into string

get_input_line(
x::T, 
input_info::Dict{Symbol, Tuple{Int64, Int64}}, 
n::Int) where T

get_input_line(
x::T, 
input_info::Dict{Symbol, Tuple{Int64, Int64, Int64}}, 
n::Int) where T

This function takes a cap18 input struct, and outputs the line string for the .dat file that the CAP18.exe file uses.

parse_to_string(x) = string(x)
parse_to_string(x::Bool) = string(convert(Int, x))

Parses an object type to a string type. For a boolean type, it parses as 1 or 0.
